Adds support for the Soundcore Boom 2 Plus (A3134).

Features

• Battery level and charging state
• Firmware version and serial number
• BassUp
• Equalizer with the 4 presets of the official app and a 9 band custom profile (-6 to +6 dB)
• Lights on/off, brightness and 8 effects

Notes

• Commands, preset curves and effect ids come from an HCI capture of the official app
• The state update packet carries the custom profile even while a preset is active, so the active preset's curve comes from the preset list
• Changing the effect or the brightness turns the lights on
• The speaker also offers the RFCOMM service 0cf12d31-fac3-4553-bd80-d6832e7c3134, which leaves state requests unanswered, so the module pins ...7b3134

Testing

Tested on firmware 03.12 with the CLI, the desktop GUI and the Android app.
