`minusEqual` overloads

== Synopses

Declared in `<bdlc_bitarray.h>`

MINUS (subtract) from the bit at the specified `index` in this array the specified `value` (retaining the result). The behavior is undefined unless `index < length()`. Note that the logical difference `A ‐ B` is defined to be `A & !B`.

Bitwise MINUS (subtract) from the specified `numBits` in this array, beginning at the specified `dstIndex`, values from the specified `srcArray` beginning at the specified `srcIndex` (retaining the results). The behavior is undefined unless `dstIndex + numBits <= length()` and `srcIndex + numBits <= srcArray.length()`. Note that the logical difference `A ‐ B` is defined to be `A & !B`.
