@brief : Initializes the L4445A Switch Driver Object, with default switch delay of 0.25 seconds.
@param : gpib_addr : GPIB address of the L4445A Switch Driver. Generally it's set to 9.
@param : switches : Python dictionary keyed with a tuple of (bank_no, switch_no) with values
of the switch model number used on the 34945EXT board using the
Y1150A switch control for N1810UL,
Y1151A switch control for L7206A,
Y1152A switch control for 87206A
The bank no. and switch no. on the bank is used in combination as a key.
The range for banks is [1, 2, 3, 4] for 34945EXT = 1,
[5, 6, 7, 8] for 34945EXT = 2, and so on.
@param : drive : Drive source for the 34945EXT module (master only)
@param : delay : Delay between switch transitions.
@param : self_test : Run Self Test after initialization.
@example: L4445A(9, switches = {(1, 1) : 'L7206A', (1, 2) : 'L7206A', (2, 2) : '87206A', (3, 1) : 'N1810UL', (3, 2) : 'N1810UL'})
@note : If more than one 34945EXT is used in a daisy chain format, then the bank number
needs to have an offset of the total number of banks from the previous 34945EXT modules.
