fix: handle big integers in incoming events

[lance]

An event may have data that contains a BigInt. The builtin JSON parser for JavaScript does not handle the BigInt types. The introduced json-bigint dependency (34k) does.

@cardil I have added an environment variable to enable the json-bigint module. I'm not a huge fan of this approach because the check is made for each call to the parser. The library does not have an obvious place to set flags or other static values. An alternative approach would be to add this as an option to the HTTP.toEvent() method, but that changes the method signature resulting in a lot of small changes all over the codebase.
