* Same generic bloc for operations
* Capture the stream of data and retains accumulator in memory
* Mirror memory for CPU readout

wip: initial commit

wip: Now a more generic bloc

wip: Add average tables to RDL

wip: integrate ma for oe in toplevel

wip: first corrections for simulation, alpha declared in package

wip: fixes for simulation

wip: fixes, secondary memory is smaller, no decimal part

wip: true rounding before wrinting to secondary memory

wip: Add average for PSC command

wip: fix sign extension on average orbit read

* A simple threhshold comparator on data output.
* When Thresh is reached, disable correction (keep value).
* User can unlock the situation via control bits.
* Same threshold for all pscid.

* The corrector contains 4 coefficients that are enought to make a
  lag-compensator or lead-compensator
* Change the name of the block to erase "pi"
* Update the simulation data

!! Still error on simulation, to be fixed

* Tie version register
* Import lib
* Copy data input before simulation

* This avoid a nasty bug in GHDL (LLVM backend) which doesn't work well
  with files with same names. We have another file named that way with
  DESYRDL.

* Also change the package constant declaration, add a few. All
  mathematic will be done outside of the package.
