Hack Browser_SDCard_ROMv2_v1.gbas to fit in Pro Micro memory #229

My mistake. The revised version of the sdcard browser didn't fit in the pro micro rom. This version makes it small enough.

Note that I gave up on ROMv1 because FindLoader does not deal with ROMv1 either. The big gain was to check only the high byte of loaderExec to for checking DEVROM variants. Nevertheless I had to reorder some ifs to optimize the && and &.

Bad news are:

I do not own a pluggy reloaded and cannot test. One needs to test...
I do not know how to test for the ROMvX0 version that put SYS_ReceiveSerial1 at 0xa7 instead of 0xb18..
