Implement TryFromIntError conversion for AnchorError

[CanardMandarin]

I noticed it was a bit painful to cast integers with try_into and try_from because you have to either unwrap() or map_err(||).

What about implementing TryFromIntError for Error so we can use the ? operator?

A member of the Team first needs to authorize it.

Before we merge, could you add a test case for this here?

[CanardMandarin]

Sure! I have added a test case.

Please also add the new error variant in TS package:

• anchor/ts/packages/anchor/src/error.ts

  Line 308 in 14309ea

  export const LangErrorCode = {

• anchor/ts/packages/anchor/src/error.ts

  Line 402 in 14309ea

  export const LangErrorMessage = new Map([

My bad, I should have thought about it!

Thanks but CI has a formatting error now. Please run yarn lint:fix.

Also, it might be good to include this feature in the CHANGELOG, otherwise it would be hard to discover.

Feel free to modify the changelog entry if the description is not clear.
