Use nom 7.0.0-alpha1 to avoid issues with dependencies.

[damirka]

Hey! We use this crate and abnf crate in Leo language: https://github.com/AleoHQ/leo

---

Recently, there has been inconsistency across community due to updates in nom, bitvec and funty.
Bumping to 0.7.0-alpha1 solves the problem and makes it work. I do understand that it's an alpha version and might not be considered safe, but that's the only solution for now.

Also adds Cargo.lock to the git to maintain best practices.

Hello! Thank you very much for your PR! Basically, I am fine using an alpha version of nom if this solves real-world issues. However, I would also like to understand what do you mean with the inconsistencies. I would be very glad if you could explain!

From my understanding we do not want to include the Cargo.lock file, see https://doc.rust-lang.org/cargo/faq.html#why-do-binaries-have-cargolock-in-version-control-but-not-libraries.

Could you also rename the commits, such that they match the changes? Otherwise it looks like you bump nom to 0.6.5.

It would also be nice to increase the abnf-core version some more. I like to keep it below 1.0.0 for now, so 0.5.0 would be more appropriate.

What do you think?

@duesee here are two links for a context:

• Build failure traced back to old commit ferrilab/bitvec#105

Thanks! Didn't know. I will return .gitignore for a lock file.

Will do.

Sure, will update.

Thank you! One more nit: could you make it so that the .gitignore file is not part of the commit and also set the commit message to "Use nom 7.0.0-alpha1 to avoid issues with dependencies"? I am happy if this solves a real issue, but also want to make sure that the commit history is comprehensible.

Btw, I tried to do the changes for you by editing the commit, but somehow I were not able to keep you as the commit author. So it would be better if you could do this:-)

@duesee Done. If that's your last request, then ready to merge. 👍
