feat: Handling of "inf" and similar NaN values

[edgarrmondragon]

Feature scope

Taps (catalog, state, stream maps, tests, etc.)

Description

For example, the Postgres NUMERIC type supports the following:

In addition to ordinary numeric values, the numeric type has several special values:

Infinity
-Infinity
NaN

Python clients usually represent those as math.inf, -math.inf and math.nan respectively. However, for interoperability reasons these NaN values are not supported in JSON or JSON Schema.

Currently, they cause the tap to crash if present, during serialization. This library uses simplejson, so the ignore_nan parameter is available to make the values null but it's unclear whether this silent data loss behavior is preferable to crashing.
