fixbaserom.py: Add support to v64 format and improve performance (#629)

Browse source 
* Add byte swap for v64 files

Signed-off-by: angie <angheloalf95@gmail.com>

* Reduce `len` function calls

Signed-off-by: angie <angheloalf95@gmail.com>

* Optimze a bit the byte-swapped v64 format

Signed-off-by: angie <angheloalf95@gmail.com>

* Strip the overdump before doing the byte-swap

The previous way wasted time by byte-swapping data that would be discarded anyway.

* Swap twice the bytes per cycle to improve performance

Signed-off-by: angie <angheloalf95@gmail.com>

* Read and write 16 bytes at a time and specify explicit endianness

Reading more bytes per cycle allow to speed up the swapping proccess

* Add v64 compatibility in the Readme

Signed-off-by: angie <angheloalf95@gmail.com>

* Read whole file as little endian and write it as big endian without the loop
