Hacky Lib Conversion

[Kakapio]

Primary issues:

1. CLI config serialization had to be stripped out since that wasn't needed for a library crate.
2. The blocking run-time was a pain so in production I just spawn a blocking tokio task whenever this crate is called.

Hi @Kakapio , I am currently unable to address this PR, I am transitioning to a new career and won't have the time for a while.

I recommend forking this repo or perhaps "vendoring" the needed code. When I have time in the future I would love to extract out a "liblnr" library that could be used by this lnr library and anyone else who needs it.

Hey Alan,

I already forked it and am using it. It's a useful crate. No worries, good luck with the career change!

Thank you,
Kakapio
