Fix encoder setting p.mem issue

[zxkmm]

• Previously I misunderstood how p.mem works and it seems the default should be false.
• removed useless enum and use bool, and use comment everywhere to indicate, because with enum there would be too many useless implicit cast and misleading people (I guess).

Looks good.

I just registered, maybe I'm writing in the wrong place. I installed this firmware, I really liked it, but I found something wrong. If you go to transmit > RDS and just click send, everything works, but if you change the text, an error often occurs.

Indeed, a closed Pull Request is not the place to ask for a question.
You may want to open a new issue and/or ask on Mayhem's discord, #question-and-help channel.

Anyway regarding your issue, I could not reproduce it on my device.

Please consider when opening your ticket to:

• specify firmware version
• provide a detailed step by step way to reproduce your crash
• if on discord, provide a video showing the problem

Thanks.
