Allow integer types to be treated as the strings pendo sends

[cosimon]

Description of change

Pendo will report custom metadata fields to have a type of integer but when the tap receives the data it comes in as a string containing a decimal value. This change adds fallback types for custom metadata integers.

Manual QA steps

• Ran on a connection that was failing due to transformer errors because the type did not match
