Learning golang, writing a simple app to interface with an HTTP API and generate emailable reports from an actualbudget instance

# TODO
- [ ] Fetch the desired budget file
- [x] Trigger a bank sync and see if we can wait for it to finish (looks like it's a blocking call so we can safely sync before reports)
- [ ] Fetch the category information for each category as well as the overall groups
- [ ] Compile a email-friendly report of the information
- [ ] Send the email to the desired parties via SMTP
