add DONGLEMAN module

[israpps]

Purpose:

• Support COH-H10020 Security Dongles with homebrew MCMAN
• Read COH-H10020 and SCPH-10020 simultaneously

TODO:

• get confirmation that it works on real hardware
• Check if arcade SIO2MAN has any difference
• Check if arcade MCSERV has any difference

Optional:

• fix semaphore feature if dogbait does not work

notes:

• arcade SIO2MAN diffs:
  • version matches XSIO2MAN v2
  • allows thread priority change via args (param seems to be: thpri=new_priority)

homebrew xmcman implementation of mcman_getcnum can't cause the 0xf fixed return value of dongleman in any way:

Port	Slot	final cnum
0	0	0x0
0	1	0x1
0	2	0x2
0	3	0x3
1	0	0x8
1	1	0x9
1	2	0xa
1	3	0xb
