We need to rebuild the binary whenever the plugin has changed.
Previously we were not doing this if the binary already existed. This MR
adds an override parameter to the build() function which will force a
rebuild even if the binary already exists.
The README has been updated to note that this parameter should be used
for Packer/Lazy, and when someone is troubleshooting. It won't be passed
in to the build function during the normal setup call.
Should address #55
BREAKING CHANGE: This MR addresses an underlying issue with the original implementation in regards to detecting line numbers for comments.
As such, this is a major breaking change. The setup function signature has changed, please review the `README.md` for the new arguments. The delta pager has also been added as a dependency: https://github.com/dandavison/delta
There will be future work to implement a native solution for parsing changes and line numbers.
