More mapper updates (#607)

Browse Source 
* M061: Add CHR-ROM variant.

* M227: Make DIP switch change only apply to submapper 1

* M242: Only assume DIP/solder pad read when A0-A7 are zero, corrects ET-187 and Xing-2462. Initialize M227's and M242's DIP switch setting on Hard Reset.

* M052: Support CHR-RAM-less variant of submapper 14.

* M364: Correct the outer bank register's address mask, for LT-953 multicart.

* M047: Supprt larger-sized multicarts using a compatible PCB. Reset to menu.

* M360: Add submapper 1.

* M221: Rewrite, add submapper 1 variant.

* M288: Remove bank masks to allow for already-existing larger cartridges.

* M411: Add submappers.

* M417: Add submapper 1.

* M115: Add multicart functionalities.

* M201: Simplify and correct the power-on value. CF-043, mentioned in the source code comment, needs no submapper; just a correct header with Horizontal mirroring.

* M200: Correct the power-on value.

* M432: Add submappers to distinguish three variants.

* Add mapper 412.
