Revert "Skeleton Custom Inst Module"

This reverts commit 6ed5199e81110e0ddbe6fc5cc25e49e98a0da183.
Initial skeleton implementation
Cleaned up weird characters
Updated scripts
Untested NIOS custom instruction
Untested floating point determinant
Merge branch 'hw-det' of https://github.com/lawliet89/DSDCourseWork into hw-det
Reading previous invocation data from RAM. ???
Initial attempt at combining the code. Compiles, but never finishes execution
Random bullshit
Commit of fp_det/vhd - many warnings - however can probs ignore them - they're only latches!
Removed all latches - apparently synthesise + latches = bad day
Problem with FSM - doesn't move from read_data to mult1
Now reading correctly from SDRAM, or so one would hope.
Merge branch 'hw-det' of https://github.com/lawliet89/DSDCourseWork into hw-det
Refactor, but still seems to give late output
Corrected RAM read timing issues
Changed code to attempt to work with calculation fp_det entity.
New Gitignore entries
