Support new key types in Yubikey 5.7 firmware

[smlx]

Yubico have announced new firmware with expanded key type support. They've also added support to their tooling.

Would you accept PRs to add these new non-standard key types once hardware is available to test them?

Happy to add them! One note is that I don't have test hardware. If it's possible, it might be nice if Yubikey would consider contributing a device to development.
