[stevo]: adds a bunch of pad frame commits, as well as beginning work on clocking annotations and constraints * start add io pads pass * save progress adding yaml pad info * saving some semi-presentable work -- parses yaml for pad templates and associates templates with ports * added black boxes to the module; still need to hook up * added supply pad yaml example; added option to not include pad for an IO, blackboxed that cat + bit extraction functions * rewrite createbbs and some other parts of the transform * finally got blackboxhelper to work -- seems there was a typo in the firrtl pass (?) have not connected them up properly in the padframe * finished first version of pad transform; need to add bells and whistles + special case stuff * made a bunch of changes in firrtl to shorthand things * done with padframe for signals * started major refactoring; first of pad yaml stuff * forgot to update verilogTemplate -> verilog * rename ParsePadYaml -> ChipPadsYaml; moved some stuff * separated out stuff that describes pads i.e. direction, type, side * forgot to update import for yamlhelpers * trying to make the process of creating annotations more structured * saving annotation helpers but prob better to switch to yaml * saving changes -- reworking annotations * fixing some bugs; properly annotated ports with pads * annotate supply pads * lesson (re)learned. cleaned up constants * finished adding supply pads to pad frame; still need to generate io file * also committing updated transform; still without io file * big typo was causing pad verilog files not to be generated * verilator passes with transform; had to fix verilog bb typo * added unused pads; added more thorough tests + did visual inspection of output; made some port types more explicit * renamed files/classes to be clearer * started creating pad io template * update spec so that transform order matters * get rid of logger * went around in circles with blackboxhelper + way to annotate * finished adding + testing pad.io creation * starting clkgen pass -- made model for asynchronously reset clk divider + wrappers for programmatic bundling * temporarily locating albert's utility functions here * saving work on clk constraints * redid input config passing -- pass in tech directory instead; seems like getting clk sink, src, and relationship works * not done; need to pause to do tapeout-y things. the clk gen pass gets all the clks and their sources, but i need to build a proper graph to handle clks coming out of muxes

Useful utilities for BAR projects
Passes/Transforms that could be useful if added here:
- Check that a module was de-duplicated. Useful for MIM CAD flows and currently done in python.
