Subject: Do not return a reference to a u64 in rust-lightning-invoices
X-Git-Tag: v0.0.14~9^2~3

Do not return a reference to a u64 in rust-lightning-invoices

There is generally never a reason to return a non-mutable reference
to a u64 vs just copying it, same applies here. It makes the API
slightly less consistent, but is easier to map in bindings and just
makes more sense.
