Missing requirement for pymssql

[hohonuuli]

Build failed when building wheel for pymssql. The workaround is to install freetds (eg. brew install freetds on macOS). No biggie, but may need to add a note in the README. The error is:

Building wheels for collected packages: pymssql
  Building wheel for pymssql (pyproject.toml) ... error
  error: subprocess-exited-with-error
  
  × Building wheel for pymssql (pyproject.toml) did not run successfully.

@hohonuuli I'll add a note to the README.

@kevinsbarnard Can we close this as completed?
