#2935) (#2936)
* TruthTable improvements: structural equality and delete sort (#2935)
We had implemented equals, but not hashCode. This commit also changes
the implemental of equals to just use the underlying values instead of
wasting the compute calling .toString.
Delete TruthTable.sort, it is unused.
(cherry picked from commit b5d9c08b2d0994b94df2380425282206fe1f25bc)
* Restore and deprecate TruthTable.sort

* Fix BitSet decoder API when errorBit=False
When errorBit is set to False, the original code will return
`Unit` which will be `()` in interpolated string.
* Add testcases for both errorBit cases in BitSetSpec

#2612) (#2620)
* Refactor TruthTable.apply and add factory method for Espresso (#2612)
Improves performance of creating TruthTables by processing entire BitPats
rather than individual bits. New TruthTable factory method enables
constructing TruthTables with semantics of OR-ing output BitPats together
rather than erroring when multiple terms have the same input BitPat.
This alternative factory method matches semantics for the output format
of Espresso.

BitSet is a new experimental parent type for BitPat.
It enables more complex operations on BitPats.
