fix: enumerate known short phone numbers instead of matching all 3/5 digit numbers (#283)

Replace phone_digits**3 | phone_digits**5 with an explicit phone.tsv
list of known short numbers (110, 119, 120, 12306, 10086, etc.).
This fixes 3-digit numbers like 500 being read as 五零零 instead of 五百.

11-digit mobile numbers (phone_digits**11) are unchanged.
