Extend multiple-term Find & Replace to <=py3.9

[jkroll-deepgram]

Previous PR (#99) relied on the | union operator, which is only supported in >=py3.10.

Existing code throws the follow error when importing from deepgram import Deepgram (using 3.9.17):

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "39env/lib/python3.9/site-packages/deepgram/__init__.py", line 2, in <module>
    from ._types import Options
  File "39env/lib/python3.9/site-packages/deepgram/_types.py", line 54, in <module>
    class TranscriptionOptions(TypedDict, total=False):
  File "39env/lib/python3.9/site-packages/deepgram/_types.py", line 85, in TranscriptionOptions
    replace: str | List[str]
TypeError: unsupported operand type(s) for |: 'type' and '_GenericAlias'

Need to rely on the Union operator to support 3.9 and earlier. I tested this change in 3.9 and confirmed that the Deepgram import works successfully, as does making a call against Find & Replace with multiple terms.

from deepgram import Deepgram
import json
import asyncio

DEEPGRAM_API_KEY = '<key>'

AUDIO_URL = 'https://static.deepgram.com/examples/Bueller-Life-moves-pretty-fast.wav'

async def main():
	dg_client = Deepgram(DEEPGRAM_API_KEY)
	response = await dg_client.transcription.prerecorded(
		{ 'url': AUDIO_URL},
		{
			"model": "nova",
			"smart_format": True,
			"replace": ["fast:slow", "miss:snooze"]
		},
	)
	print(response["results"]["channels"][0]["alternatives"][0]["transcript"])

asyncio.run(main())


Yep. I said it before, and I'll say it again. Life moves pretty slow. You don't stop and look around once in a while. you could snooze it.

Tests also pass - pytest --api-key <key> tests/
