Various PSX fixes

[t-b]

• FFT size fix using 2^l + 3^k logic
• psx accepted average fix: return real amplitude for double expontential
• average fit for reject, undet, all, add into column on the right
• Add default values for filter frequencies:

sweepFilter: Default values for low/high, order defaults to 4
low cutoff  = 1 / (3 * pi * riseTau)
high cutoff = 1 / (3 * pi * decayTau)
deconvFilter: Default values for low/high, order defaults to 4
low cutoff  = 1 / (4 * pi * riseTau)
high cutoff = 1 / (4 * pi * decayTau)

• Add y value from PSX_CalculateOnsetTime into psxEvent and psxstats
• add the fit results as a wave in psx
• the "block size" control doesn't respect the "current combo" checkbox state
• add peakThreshold in () behind numberOfSDs in the JWN to document it
• Add V_mode and all other missing entries from StatsQuantiles to postProc output for stats in psxStats
• Prep PR: PSX prep #2471
• TB: Dig up store/results code from slack
• Tim provides Poc for figuring out psxKernel parameters from scratch
• Approval from Tim
• Fix conflicts
• windows position after move is not kept on pressing display, psx plot only does not reproduce
• Fix commits a bit
• Fix tests
• Add tests for new functionality
• Update ihf documentation

Old Todos

So this should be ready for a first test. I've adapted `psxKernel` and `psxStats` to allow passing in multiple selections.

• Fix assertion, https://aiephys.slack.com/archives/C06P3MYEV6H/p1742330027060869
• PSX multiple selections (only that) #2376
• Yesterday, we chatted about moving the baseline search before peak_t, and I think
  that still makes sense. The baseline search shouldn't search past the previous
  peak_t. With the baseline_t of the event available, PSX_CalculateEventPeak, instead
  of using prevDeconvPeak_t to constrain the search, can use the event
  baseline_tinstead. The above makes adding a peakfinding operation, which I suggested
  yesterday, unnecessary.
• Tweak accept fit average logic: The start point for the fit should be calculated via rise time calculation (20% of amplitude, add control "fit start amplitude"). Use that for onset and peak methods.
• Debug session with Tim
• Polish code
  • // TODO add vertical dashed lines at positions
    // 3 checkboxes to turn all of these on/off below suppress update
    // peak_t
    // baseline_t
  • Fix assertion when restoring PSX panel with accepted fit checkbox checked
• Add three taus to stats
• Wait for Tim's changes
• Fix function comment PSX_AppendTracesToAllEventGraph
• https://aiephys.slack.com/archives/D6WGZV2V8/p1743629846161639
• Fix slow/fast tau
• Excel import could be better, see UpdateInfoButtonHelp: Set machine-readable text for C&P #2424
• Commit cleanup
• Add psxBPSweepFilter (BP = bandpass) and back down order for sweep/deconv. Handle the high/low frequency input arguments for the user such that the filtering is always bandpass.
• Rename psxDeconFilter to include the filter type acronym (is this also a bandpass filter?). Manage the frequency arguments for the user such that it doesn't matter what order they are provided.

# psxSweepFilter(lowFreq, highFreq [, order = 6])
# back down on having nonfinite values in filtered data, order -2, output passing order
# back down on deconv order as well, same approach
# use code from Tim to determine the highest possible, reapply that order to all sweep data

• Output all x/y axis labels for multiple operations with with, see SweepFormula: Groups multiple x-axis labels #2423
• Later: Decide later on about support for multiple properties in psxStats, see psxstats: Should accept an array of properties #2422
• SweepFormula: Groups multiple x-axis labels #2423
• UpdateInfoButtonHelp: Set machine-readable text for C&P #2424

@t-b I also tested pasting the average fit results into Excel. The row formatting is correct. However, Excel plots all the columns in one column. Excel is dumb. To correct this, paste into Excel, select the cells, select Data from the menu, select Text to Columns, and select the appropriate delimiter in the Excel pop-up GUI.

@t-b there may also be issues with the indivdual decay tau values. For example in this case I'm getting a negative weighted tau.

@t-b I've opened a new pull request, #2608, to work on those changes. Once the pull request is ready, I'll request review from you.
