Hex encoding the Data field in the SASL responses made debugging SCRAM
more difficult than actually helping.

This change introduces a new zerologadapter that allows
users to pass the actual logger via context.Context. Especially HTTP
middleware might choose to use `(*zerolog.Logger).WithContext` and
`zerolog.Ctx`. Allowing users to extract the logger from the context
keeps the full enriched logger available when pgx emits logs.
WithContextFunc adds possibility to get request scoped values from the
ctx.Context before logging lines.
WithoutPGXModule disables adding module:pgx to the default logger context.
The shopspring/decimal package provides a NullDecimal struct intended
for use with nullable SQL NUMERICs and numbers. It has Scanner and
Valuer implementations already, but adding it to this package allows
it to be used with the binary encoding as well.
The implementation is very straightforward, but the tests have been made
slightly more complicated. The previous version wasn't testing the
decimal.Decimal cases, and this change adds those as well as new
NullDecimal cases. I've added some logic to the test harness to catch
these as you need to use the Equals method to properly compare Decimals.
Bug was advancing the read pointer by the length of the value even if it
was a NULL value. Since NULL is indicated by a -1 length it actually
decremented the read pointer.
