pkcs11 token support

[embetrix]

Hi,

can HWI support a PKCS#11 Token aka. HSM with secp256k1 curve support ?

Additional devices can be added so long as they meet our policy for device support: https://hwi.readthedocs.io/en/latest/devices/index.html#support-policy

As this is an open source project, pull requests are welcome.

[embetrix]

is there a skeleton code to integrate new HW ? I will be happy to add make some requests

New devices need to implement the HardwareWalletClient class with their implementation living in hwilib/devices. You can look at the device implementations already there for reference.
