input: vcd: support 1 bit vectors 

Use the new process_bit() function to parse 1 bit vectors, too.

This is the first step to fix bug #723. Minimal testcase vcd:

$timescale 1 ns $end
$var wire 1 n0 addr_0 $end
$var wire 1 n1 addr_1 $end
$enddefinitions $end
#0
0n0
b1 n1
#1
1n0
b0 n1
#2
0n0
b1 n1
#3
1n0
b0 n1
