add MFT-SEMA100 board
look at this PR for an example of readme.md, images, info required for documentation: (xls doc not required) https://github.com/ArduPilot/ardupilot/pull/26854 also how commits are organized it is usually a good idea to make the board_types.txt a separate PR to reserve the board id since it might be taken while this PR gets finalized and documentation provided....avoids having thee change your board id at the last minute when this gets about to be merged
@EternAlmox will review docs tomorrow...having hospital procedure done today
Started my review, but before I can complete it I need the mapping from the marked TXn/RXn pins on the board to the CPU's uarts...the docs are inconsistent....please provide a list and then I can finish the review
also, the current definition leaves no UART with full DMA on TX and RX so some RC protocols will not be supported (CRSF,ELRS,etc.)...and the second GPS does not have DMA, requiring ALL GPSes to be restricted to 115K, this needs to be changed
