Auto Splitters: Add optional cache for memory mappings

[EXtremeExploit]

Mainly an experimental feature (i think values 0 and 1 shouldnt be experimental since i havent seen any problem with them) i liked to see for some games that dont have a fixed game state update rate where a lot of reads happen and its VERY important to have a super accurate timer. More info is included in the docs

Performance

Performance is taken from 150 samples on a script that reads on the same module 10 times. Numbers are in microseconds

mapsCacheCycles	Average	min	max
0 (default)	8555	6850	15930
1	1148	948	3934
2	631	122	1417

Notes:

• Because values higher than 1 make some cycles completely cached the results oscillate between completely cached and 1 cache missed like this:

• Also i added the documentation for getPID on the documentation

• And an extra check for type string in case the user specifies (or doesnt) an invalid string size
