RUSTSEC-2025-0141: Bincode is unmaintained

[github-actions]

Details
Package	bincode
Version	1.3.3
Warning	unmaintained
URL	https://git.sr.ht/~stygianentity/bincode/tree/v3.0/item/README.md
Patched Versions	n/a

Due to a doxxing and harassment incident, the bincode team has taken the decision to cease development permanently.

The team considers version 1.3.3 a complete version of bincode that is not in need of any updates.

Alternatives to consider

• wincode
• postcard
• bitcode
• rkyv

It affects the bdk_file_store, although it's not meant to production usage, it's a good idea to assess the suggested alternatives and migrate to one of those.

I thinks it's fine to keep bincode unless we need some feature it currently lacks or a security vulnerability is found, as bdk_file_store meant for development only.

I'll assess the alternatives. I think is better to have some maintainers behind the libraries we are using.
