fix: remove asynchronous if from frame_alignment

fix: do not use when inside of a process

fix: remove double assignment of synced in data link layer

fix: assign lane alignment aligned and error

fix: correctly count error counts in error handler

chore: rename some ports and generics to better match function

Merge pull request #25 from Rutherther/feat/subclass-1-support

Add subclass 1 support

feat: allow changing align buffer size used in lane alignment

feat: change behavior of asserting link nsynced only on frame clk (subclass 0) and multiframe clk (subclass 1)

feat: start emptying lane aligned buffer only if not in CGS

fix: deassert sync on LMFC falling edge to match the standard

feat: add basic subclass 1 support

chore: specify ranges for all integers

Ranges are not needed inside of tesbenches.
Resolves #22.

feat: assume full synchronization after 4 correct 8b10b characters are received after 4 /K/ characters

Resolves #23.

fix: set user_data inside of lane_alignment even if ithe buffer is not released yet

fix: adjust jesd204b_link_rx to work with new changes
