Two XM3s connected

[Frambooisier]

Describe the bug
if I run the software while two XM3 headphones are connecte I got this message and I don't know if it's expected or not prepared for such case

Also reading the readme of this repo I was not sure if it's not working with XM3 and XM4 altogether or early firmware versions, considering that it's forked from project that mainly supported XM3 I think it is little confusing.

That's...quite an edge case. However handled in the current rewrite branch in 7a9c489 - please note that the legacy (master) branch releases builds are no longer supported. See also #38, #12.

Discontined legacy branch aside, XM3s and other MDRv1 protocol devices are not supported yet.

Eventual support for XM3/XM4s is planned. (for almost half a year now..) But as I personally do not have those devices, it will have to be delayed until other contributors (@Amrsatrio) could come to rescue.

Also as mentioned in #39, there exsits forks that does support XM3/4s. But beware - compatibility nor safety there is guaranteed. Use those at your own discretion.
