This adds a option to do bmaptool copy --format simg ... to convert to an Android Sparse Image format file.

Android Sparse Image files fulfill essentially the same purpose as .bmap files, but they are simpler and therefore supported in low level software (like the U-boot mmc swrite ... command). Background info on the format: https://2net.co.uk/tutorial/android-sparse-image-format

Is this a feature the bmaptool project is willing to accept? If so I can cleanup, document, unit test, etc

…mage file

Android Sparse Image files are supported by the U-Boot `mmc swrite ...` command which greatly speeds up the bootstrapping process of an unprogrammed board.
