Missing TermCursor and TermCursorNC for Neovim

[seb-mueller]

Similar to this issue, TermCursor and TermCursorNC highlight groups are missing in the current project. They define how terminal cursor should behave in neovim terminal buffers.

This is how it can be tested:

:terminal
:hi! TermCursorNC ctermfg=15 guifg=#fdf6e3 ctermbg=14 guibg=#93a1a1 cterm=NONE gui=NONE

But it would be nice to have it integrated into the colorscheme itself.

I came accross this watching this episode of vimcast:
