Abstracing 'Patch' and 'Put' in a single 'Update' function

[nicolasnascimento]

The Airtable API provides two ways in which one can update a record, PATCH (not all fields) and PUT (all fields). I think deciding which type of operation to perform should be decided by the library and made abstract to library users.

I propose making 'patch' and 'put' (offered by the API, but not available in the library yet) private and creating a general 'update' function which decides which of these operation to perform.

This change appears to be feasible and not too time consuming.

I was reading the docs for Airtable API and apparently now you can update all fields using a PATCH operation.
The difference is that PUT is Destructive and replaces the entire row.
Given that, I think this now is a matter of renaming the method to update
