Subject: Support mapping `Readable` `impl`s outside of the `lightning` crate
X-Git-Tag: v0.0.111.0~1^2~7
X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=f180d14d64d6513b9c96573075680b2b1b9b92f3;p=ldk-c-bindings

Support mapping `Readable` `impl`s outside of the `lightning` crate

In order to map `Readable` `impl` blocks in crates other than the
`lightning` main crate we simply have to update the type references
to include crate name, which we do here.
