fix(espefuse): Fix compatibility with Bitstring>=4

Browse Source 
bitstring==4 dropped class alias for BitStream. BitString was just an
alias in all supported bitstring versions:
https://github.com/scott-griffiths/bitstring/blob/bitstring-3.1.6/bitstring.py#L4247

Closes https://github.com/espressif/esptool/issues/797
