[Feature Request] Ability to configure bigint serialization

[dnechay]

Issue description

Atm pino uses safe-stable-stringify that is configured with bigint: true to serialize values when JSON.stringify fails with errors. It can lead to tricky behavior, e.g.:

• Tricky BigInt values displayed incorrectly pino-pretty#633
• if too big number gets logged as "number", it might fail to be correctly parsed in some 3rd party systems (e.g. in logging providers)

Suggestion

It would be nice to have some sort of bigint: replacer | false option in pino configuration, that would:

• when false: disable any serialization of bigint and re-throw error from JSON.stringify, so pino users are explicitly warned and can decide how to serialize bigint
• when no value - use some default behavior (now - serializing to "number")
• when custom replacer is provided - use it
