…sing RTT. How it works: - Debugger writes magic number into a RAM address. - Debugger resets CPU - Application read the magic number - If set then don't start normal application, instead start RTT flash loader. - Upload the filesystem or dump it from target. - Debugger issues a reset. - Application boots as normal.

Fixes #64
How it works:
To create a littlefs filesystem using everything placed in
src/images/binaries/and upload it to external SPI Flash:west upload_fsTo dump the fs from target:
west upload_fs --type lfs --read_file filename_to_save_toOR
west upload_fs --type raw --read_file filename_to_save_toFolder options
filename.binput intolvgl_lfsgoes into littlefs filesystem into one partition of external flash.lv_img_set_src(img, "S:filename.bin");west upload_fs --type rawfilename.binput intoSgoes into a basic readonly filesystem into one other partition of external flash.lv_img_set_src(img, "/lvgl_lfs/filename.bin");west upload_fs --type lfsWhich one to use?
For now those options are mostly for experimentation. Using littlefs may be faster due to littlefs caching. However the other custom filesystem allows us to do more optimization for ZSWatch in the future.
