Attachment sync not working on Deno runtime

[sgwilym]

What's the problem you want solved?

Syncing attachments larger than 256kb breaks with peers syncing with PartnerWebServer / PartnerWebClient running on the Deno runtime. This is being caused by Deno not sending all messages.

Is there a solution you'd like to recommend?

For the time being users should stick to Deno 1.26.2, which does not drop WebSocket messages.

Deno need to fix their WebSocket implementation. I have created a issue for these unsent message: denoland/deno#17332

Seems like this will be fixed in Deno 1.30 thanks to this: denoland/deno#17480
