Allow disabling of indefinite length array/map decoding to save object code

Allows defining of QCBOR_DISABLE_INDEFINITE_LENGTH_ARRAYS to save 200 bytes of object code for the smallest decode configuration.

Added a few more tests related to bstr-wrapped CBOR.

Some code tidiness fixes (that don't change semantics)
