0.8.0

There is a major rework on Source File Extract, which is a breaking change and requires users to update their configuration files and the usage of generated Nix expressions.

1. Now both extract and cargo_lock (renamed from cargo_locks) options accept a list of zsh style globs.
2. ExtractSrc rule now copies all matched files to the output directory and generates a mapping between relative paths in the output directory and original paths in the source repository, rather than loading them into memory as text files. This makes extracting binary files possible.
3. There are several structural changes in generated Nix expressions. See #139 for details.
