TimeParser should properly handle $(x;name='band') by using "band" as the key

I was expecting that if I called:

```
from java.lang import HashMap

tp=TimeParser.create('T$Y$j_$H_$(x;name=band)KHZ_WBB.PNG')
e= HashMap()
print tp.parse('T2000037_18_1025KHZ_WBB.PNG',e)
print 'band='+e.get('band')
```
that it would print "band=1025", but it doesn't.  The map `e` just has the key x in it.
