so we don't need pyrcc5, which is not deterministic,
and so we don't need the submodule for the icons
based on electrumsv/electrumsv@bf8802c2eaf0bf75565b5423a95bcb85ec7eb781
Outdated firmware error messages were originally raised from
create_client, which would mean that a client for an outdated device
would not be created.
This had a number of undesirable outcomes due to "client does not exist"
being conflated with "no device is connected".
Instead, we raise in setup_client (which prevents creating new wallets
with outdated devices, BUT shows them in device list), and python-trezor
also raises on most calls (which gives us an error message when opening
wallet and/or trying to do basically anything with it).
This is still suboptimal - i.e., there's currently no way for Electrum to
claim higher version requirement than the underlying python-trezor, and
so minimum_firmware property is pretty much useless ATM.
we should not raise generic Exception when wanting to communicate with
the user. it makes distinguishing programming errors and messages hard,
as the caller will necessarily need to catch all Exceptions then
[trezor] connecting to device at bridge:hid...
[trezor] connected to device at bridge:hid...

It was disabled in 680df7d6b6 due to #4421,
but that has since been fixed.
Also related is #4060; and now that that is closed, the bridge transport
is not proxied anyway.
