WIP reverse codec of elf2uf2 back-converting uf2 files to compressed elf files for memory usage analysis
[elf2uf2]
* Read the ELF header and detect whether this is a RAM binary or a Flash binary (???)
* Check the Program Header Table (PH Table Entries) for their address ranges if it has any
* Do some manual platform specific error correction and bug fixing on the image
* Fail early if slight incompatibility detected, otherwise write the magic section to UF2
[uf22elf]
* Read the UF2 and treat the entire contents as the .text GNU Section in the ELF
* Optionally pick out strings and place them in the .data GNU Section in the ELF
