[Gateway] bigint fields should be sent as JSON integers, not strings

[ahmouse15]

Describe the bug
Spacebar incorrectly sends bigint fields as strings instead of integers in JSON. This affects client parsing of a User object's flags, public_flags, and purchased_flags at least.

To Reproduce
Steps to reproduce the behavior:

1. Run Spacebar Gateway
2. Observe payload from READY event emitted by Gateway WebSocket after logging in
3. user.public_flags has e.g. "64" instead of 64

Expected behavior
bigints should be sent as integers. See the sample response from the Discord API docs here: https://docs.discord.com/developers/resources/user#user-object-example-user

System Information (please complete the following information):

Additional context
This bug prevents Dissent from connecting to Spacebar instances (likely among other bugs).

Sample response from Spacebar gateway:

{"op":0,"t":"READY","s":0,"d":{"v":9,"user":{"username":"admin","discriminator":"4332","id":"1471412073861865509","public_flags":"31",...}}

there used to be a time when we kept flipping the flags columns between int and string for those reasons :') - the same applies to flags as far as i can tell too.

Has discord changed it? Which type is correct?

[ahmouse15]

It's also odd because everywhere I look in the Spacebar source, these fields are always typed as numbers.

Upon testing, I can also confirm that flags and purchased_flags are also affected.

OK I discovered that this is due to a bug in typeorm. I've opened a new issue there: typeorm/typeorm#11981

typeorm parses bigint (int8) field as strings, as opposed to integers, which is causing this issue for all bigint fields in Spacebar. A possible solution is to use a transformer: typeorm/typeorm#2400 (comment)
