BigInt serialization error in encodePostData

[zimrain]

Our React app uses BigInt in many places. Only autocapture is on, no custom events. We're getting the following: "TypeError: Do not know how to serialize a BigInt"

Source map points back to JSON.stringify call in encodePostData here:

posthog-js/src/request.ts

Line 48 in 26150b1

const gzipData = gzipSync(strToU8(JSON.stringify(data)), { mtime: 0 })
