Alas, Firefox has implemented WebSerial

[Msprg]

I just wanted to express my gratitude to @kuba2k2 for making this webserial extension. It has gotten me trough this long time gap until now, as Mozilla has Finally implemented native webserial in Firefox 151. Thank you for developing and maintaining this project. I wish you lots of success in the future~! 😊

Thanks indeed. I'd suggest adding this at the top of the ReadMe suggesting first to update Firefox to 151 and above.
