Some additional commands, buffer peeks, smaller fixes

All single-stream peek commands no longer require you to "chunk" the data as the sysmodule will do this to send large data quickly in one command. GetInfo() is now used to get the heap base to reduce overhead on all peek and poke commands.

getTitleVersion was added courtesy of @6A-Realm
Various info commands were added courtesy of @amel-am
Smaller fixes were provided by @Lincoln-LM and @ELY3M

Other smaller fixes are also included in this release.

Thank you to all the contributors.
