word preprocess

[xxoospring]

Thanks for this awesome project ! I found a preprocess issue:

print(phoney.phonize("$234.009")) 

print(phoney.phonize("$234.09"))
#T UW1  HH AH1 N D R AH0 D  AH0 N D  TH ER1 D IY2  F AO1 R  D AA1 L ER0 Z  AH0 N D  N AY1 N  S EH1 N T S

the two lines return the same phoneme sequence, but $234.009 not equals $234.09. This situation is strictly differentiated in financial scenarios.

Very thanks for this wonderful Project. It is a great work.
