feat: move all link configuration to generic instead of ports

Configuration is same for one compilation, it cannot change.
Thus it does not make sense to be a port.
Resolves #13.

fix(lane): output user_data based on current link state in lane_alignment

fix(ilas): output error if there is more than 3 multiframes

fix(ilas): do not check chksum

fix(ilas): output finished right after ils state ends

feat: remove unnecessary big buffer (3 * buffer_size) from ring_buffer

fix: update data link layer to meet changes

feat: update jesd204b_rx to new frame clock

fix: calculate octets in multiframe from input in ilas parser

fix: make char alignment work for part characters correctly

Merge pull request #14 from Rutherther/feat/add-frame-clock

Add frame clock handling

feat: reset everything in ring buffer

feat: make frame alignment output aligned octets in frames instead of octets

fix: make buffer inside of ring buffer triple instead of twice temporarily

fix(link): make testbenches work in quartus, fix old testbenches

fix(link): check that characters in ilas parser are control characters

ILAS parser did not check that characters are control characters,
