Bump chia rs 0.28

[arvidn]

Purpose:

This PR is best reviewed one commit at a time. It updates chia_rs to the latest version:

1. correct the return value from get_spends_for_trusted_block() which matt fixed recently.
2. remove casts that are no longer necessary, with the fixed type stubs
3. adjust a test to expect a slightly different error message, related to the work on error codes in clvm_rs Jack did.
