Refactoring Library and CLI

[Louis Beaudoin]

Hi, I've been looking for a way to update the content on my Teensy AnimatedGIF projects like this one without having to remove the SD card for years now, until I found your library. I just refactored it so the CLI example sketch is now mostly inside the library as a class that contains XYmodem, and most of the configuration (filesystem, serial port), can be done inside the sketch instead of needing to edit the library files. I think this library has a lot of potential to be added (with just a few lines of code!) to any project that wants to add filesystem editing in parallel with whatever they're already doing in their sketch.

I wanted to check in with you to see if this is a project you're still working on and would want to submit to the Arduino Library Manager and maintain, or if you've moved on to other things and are happy for me to keep going with it (with proper attribution). Either way, thanks for the work you've done on this so far!
