FFE - Python functions to generate and send email

[as1729]

Story: #3803

Requirements:

• Goal: Allow the python function to send the user an email with the URL to download the file. This currently exists within the cpf-reporter code and will need to be translated over to ARPA Reporter. python directory.

• Current CPF implementation: https://github.com/usdigitalresponse/cpf-reporter/blob/main/python/src/functions/generate_presigned_url_and_send_email.py

Acceptance Criteria:

• Any python code can import a generate_email function and send_email function that accepts the same inputs as seen here. These functions must return a formatted email and use SES to send the email respectively.
• This ticket does not need to worry about having access to SES. This will be handled in the python task definition in FFE - Python task to generate zipfile, upload zipfile to s3, and send user email #3911
• The email formatting should meet the specifications laid out in [STORY]: Full File Export #3803 .
• SES tags need to be added correctly so they show up in datadog.
