Passport number wrongly expanded

[darshan-naidu21]

When normalizing text for TTS, passport numbers are being incorrectly expanded into full numbers instead of digit-by-digit pronunciation.

Example:

Input: Passport number EL9568719

Expected Output: Passport number EL nine five six eight seven one nine

Actual Output: Passport number EL nine million five hundred sixty-eight thousand seven hundred nineteen

Steps to Reproduce:

Pass Passport number EL9568719 to the normalizer.

Observe that the digits are expanded into a large spoken number instead of digit-by-digit.

Expected Behavior:
Passport numbers (and similar identifiers) should be normalized into digit-by-digit speech.

Added passport, 0c98809

import malaya
normalizer = malaya.normalize.normalizer()

strings = [
  'yes, may I repeat, your passport is EL9568719',
  'ini adalah passport saya A2096457'
]

for no, s in enumerate(strings):
    string = normalizer.normalize(
        s, 
        normalize_hingga = False, 
        normalize_text = True, 
        normalize_word_rules = False, 
        normalize_time = True, 
        normalize_cardinal = False,
        normalize_ordinal = False,
        normalize_url = True,
        normalize_email = True,
        normalize_in_english=True,
    )
    print(no + 1, '-', string['normalize'])

Output,

1 - yes, may I repeat, your passport is E L nine five six eight seven one nine
2 - ini adalah passport saya A two zero nine six four five seven
