Hwi

Also available on [PyPi](https://pypi.org/project/hwi/) and can be installed with `pip install -U hwi`

Added

* Trezor and Keepkey change detection for single key (P2PKH and P2WPKH) outputs
* `device_model` output in enumerate to distinguish between different device models from the same vendor. Device model names can be provided to `--device_type`, as can the original device type.

Changed

* Trezor One and Keepkey: Close and clear previous sessions to retain behavior of allowing `--pasword` to change with each run.
* Help output will be directed to stderr. A JSON formatted error message and code will be output to stdout to align with all other HWI command outputs.

Fixed

* Provide udev rules with binary distributions so that they can be installed.
* Udev rules can only be installed on Linux.
* Output error messages and codes in more places that were missing it.

* `needs_passphrase_sent` and `needs_pin_sent` fields in enumerate indicate whether a passphrase or pin needs to be sent to the device in the next command

Changed

* Command runtime speedup by caching device fingerprints
* Keep Trezor and Keepkey sessions open so that the passphrase does not need always need to be re-entered

Fixed

* Windows 7 Binaries
* Some missing imports
* `displayaddress` when used with descriptors
