pallas-traverse depends on the unmaintained paste crate

[ginnun]

paste crate is no longer maintained,
see https://rustsec.org/advisories/RUSTSEC-2024-0436.

It would be in the best interest of pallas and its userbase (at least for us in Blockfrost) somehow remove paste from dependencies.

@ginnun Is there a natural replacement or should one got with full syn?
