Add ability to convert Motorola S-Record and Intel Hex files into binary files

[nightlark]

There might be some tricky aspects to this (what happens if it is writing a file at some high address that would result in a mostly empty multi-gigabyte file?), but would be an interesting capability. Maybe along with a config option to specify the directory should be placed in and whether the binary file should be kept around after Surfactant runs. Would also need to figure out how to handle Surfactant re-running, and what the file name and container path should be.
