This is now tested as compatible with BIP78 as
implemented by BTCPayServer.
An additional config section [PAYJOIN] is added to
manage settings for fee control in payjoin as
described in the BIP. These settings are marked as
advanced usage as they're rather complex for users
to understand and the defaults should be very safe.

Adds a new module jmclient.payjoin which implements
the full sender workflow from a BIP21 uri to a
payjoin broadcast, state is managed in JMPayjoinManager,
includes all checks as per documentation of
btcpayserver (and later, BIP78).
Added simple client and server implementations in
test/payjoinclient.py and test/payjoinserver.py
which allow a full end to end test on regtest.
Add TLS support to payjoin tests:
Note: the jmclient.payjoin module already
supports TLS by default (Agent object), but
here we add the ability to test without
certificate verification. Both test/payjoinclient.py
and test/payjoinserver.py now support TLS, but
the server needs a key and certificate in its
directory to run.
Adds BIP78 payjoin option to sendpayment.py
Users can use a bip21 uri with the "pj" field to
send a payment to a remote server.
Removes require_path_templates setting from KeyStore call
in PSBTWalletMixin.sign_psbt
