This library will need some updates now that the BIP is finalized and has been implemented in Bitcoin Core, and will be activated soon on Bitcoin mainnet. It looks to me like libtorsion still uses 33 bytes for public keys, that has been replaced with 32 byte public keys:

from bitcoin/bips#893

The tie-breaker for public keys with implicit Y coordinate is changed from square to even. This improves signing speed, and makes integration with existing key generation easier. This also has implications for BIP 341.
