We now have a solid rough draft of the 2 bit sat counter branch predictor with BTB and RAS.
...
This is not yet tested but the system verilog does compile.

added branch predictor 2 bit table + SRAM model. The SRAM model is only approximate, but it does correctly model the read and write pipelined behavior.

Due to legacy code, make pnr would print out an internal Makefile error at the end of the run. While this error was inconsequential and did not affect anything, it still needed to be removed.

The top level of the branch predictor built and compiles. Does not yet function. Missing the BTB, RAS, and direction prediction tables.

sky130 18T and 15T cell libraries removed
...
Upon noticing their size, concerns were raised about available drive space.
As 12T is the main implementation focus, the decision was made to remove 15T and 18T.
Apologies if any were interested in implementing the processor across multiple standard cell libraries for comparison.

- Cleaned up Makefile in case anyone looks inside of it.

a good thing to be doing
