Stable release

This is the latest stable release, It includes only bug fixes since 0.31.7.

Note that this version does not include config_flow:

• if you are running 0.31.7, this should be a simple/safe upgrade
• if you are running 0.41.7, you may want to wait (but you don't have to, YMMV)

If there is an issue, it should be straight-forward to roll back to 0.31.7 from this version.

With the exception of adding tests via test_homeassistant_custom_component, it contains only bug fixes, including:

• fix battery_level is extra_state_attrs (now scalar, not dict)
• lots of tweaks/fixes to the service calls

Resolved issues include (but are not limited to):

• #169 set_zone_mode - eco_boost is being set for 1 hour
• #164 send_packet - creating invalid address
• #163 set_zone_mode - broken?
• #162 Warning: Entity implements HVACMode(s): heat, off, auto and therefore...
• #157 The gateway type is not determinable, will assume evofw3
• #156 fix errors within 3110 parser
• #151 Message events listener doesn't catch as expected
• #145 fix errors within 01FF parser
• #85 send_pkt service fails with 18:000730 as destination

It uses an updated version of the ramses_rf client library:

• experimental support for evofw3-over-MQTT (see: https://github.com/IndaloTech/ramses_esp)
• improved logging: better messages, less logspam, no silent discarding of packets
• threadsafeing, parser tweaks, hardening
