Error with Old HTTP: closewrite error

[mattcbro]

This package currently runs afoul of closewrite being defined in multiple packages per this issue:
https://discourse.julialang.org/t/http-request-closewrite/86583

However it's easily fixed by just updating the dependencies and updating Mux and HTTP. I altered the Project.toml in a local cloned copy to have the compatibility section look like:

[compat]
HTTP = "0.8, 0.9, 1.5"
JSON3 = "1.1, 1.12.0"
Pipe = "1.3"
julia = "1"

Now I'm using the later HTTP and JSON3 in this project to good effect and the closewrite error is gone.
