Protocol types:

INT(x) is two bytes, big-endian, representing x, a number 0 through
65535.

STRING(s) is a representation of a string, s, represented as length and
content.  The length is a single octet, if it is 0 through 127; if it
is longer, it is two octets, holding INT(l+32640) (so that a length of
128 maps to 0x80 0x00).  The format cannot represent strings longer
than 32895 octets.

LOC is a place a card can be.  This is represented as two octets.  The
first one classifies the place, the second gives detail:

	First	Second	Meaning
	0x00	0x00	Stock pile
	0x01	0x00	Turned-up trump
	0x02	N	Nth card in player's own hand
	0x03	N	Nth card in opponent's hand
	0x04	0x00	Play-to-trick location
	0x05	0x00	Player's own trick pile
	0x06	0x00	Opponent's trick pile
	0x07	TBD	Player's own meld area
	0x08	TBD	Opponent's meld area

CARD is one byte, which represents a card ID.  This is a simple integer
from 0 to 95, one for each card of the deck.

IMAGE is one byte, which represnts a card image.  This is a simple
integer from 0 to 24.  0 through 23 represent the card images

	 +    0   1   2   3   4   5
	 0   9C  JC  QC  KC 10C  AC
	 6   9D  JD  QD  KD 10D  AD
	12   9H  JH  QH  KH 10H  AH
	18   9S  JS  QS  KS 10S  AS

while 24 represents the deck's back image.

DEAL is 0 or 1, indicating who is dealer this game: 0 means the
recipient is not dealer, 1 that the recipient is dealer.

STAGE is one octet, indicating game phase:

	0x00	Dealing
	0x01	Phase 1: recipient to lead.
	0x02	Phase 1: opponent to lead.
	0x03	Phase 1: recipient to play second.
	0x04	Phase 1: opponent to play second.
	0x05	Phase 1: recipient to meld or draw.
	0x06	Phase 1: opponent to meld or draw.
	0x07	Phase 2: recipient to lead.
	0x08	Phase 2: opponent to lead.
	0x09	Phase 2: recipient to play second.
	0x0a	Phase 2: opponent to play second.
	0x0b	End-of-hand count-up.

WHO is one octet, indicating a player: 0 is the receiving player, 1 is
the other player.
