pico appears & disappears, doesn't respond to sigrok/pulseview #44

(windows)

when i try to connect the pico to pulseview (pico connected, then pulseview opened) sometimes the pico doesn't appear in the serial port option of pulseview, not even device manager - this makes me skeptical if its my usb connection or the pico, but it's better to report it anyways just in case

on top of that, sometimes the pico just drops out, so every time i'd try to start reading from the pico via pulseview it'll just say "generic error", with nothing useful in the logs

also, not an issue but more of a suggestion/question, is there any support for infinite data acquisition? if i were to set the sample rate to 1mhz and set the samples to 1G it does what i ask for, but i'd think there was a simpler way...

got some sort of logging output:

only happens when i rename a channel, weird

So I had plans to support channel renaming, but stopped trying to implement it to try to keep my pull request more stable. I think that if you keep the initial signal name and then add additional characters after it it might work.
