More attempt to support Sony S360 reader

Initialisation of RC-S360 in mode 0
Better generic nfc-list, does not rely only on DeSelect to avoid duplicates
Restore SetParameters for RC-S360
Handle Diagnose communication test properly

Tested:
    - nfc-list          => ok except for B' & 3B
    - nfc-anticol       => fails to send raw frames before select
    - nfc-mfultralight  => ok
    - nfc-mfclassic     => ok
    - pn53x-tamashell   => ok
    - pn53x-diagnose    => ok
    - nfc-dep-initiator => ok
    - nfc-dep-target    => fails in InitAsTarget
    - nfc-emulate-*     => fails in InitAsTarget

Commands momentarily disabled for RC-S330:
    - InDeselect
    - InRelease
    - select_passive_target for B'& 3B
