0d72454776 loader: move loader into main workspace 
Add the loader into the main workspace, removing it from its own
sub-workspace. We can do this now that we can specify the linker script
in `build.rs`.

This improves IDE support, and should shrink disk storage requirements.

9e1fec4d78 emulation: update offset of xous.img 
This image file should get loaded onto SPI flash rather than into RAM,
since RAM gets cleared by the bootloader now.

5ae1e437ab sha512: fix length and 512/256 calculation 
The length is now correctly calculated, and the engine properly
completes.

Additionally, a bulk 512/256 implementation has been written that works
well enough, but will fall over if asked to compute a large amount of
data.
