Fixes #455

Revert "Split coverage and deploy jobs in static.yml to avoid env issue"

This reverts commit 0f14077d.

Clean out env passed to wasmbrowsertest in TestWasm

Split coverage and deploy jobs in static.yml to avoid env issue

Add setup-go to static.yml

Fix coverage

Add transfer notice to README

Update import path to github.com/coder/websocket

vulncheck was using slices which is only in
newer Go versions.

This will create easily solved breakage on updates but
I figure it's best to pull the band aid off as early as possible

fix closenow race

Context can be cancelled by parent. Doesn't indicate the CloseRead goroutine
has exited.

See #326

Far simpler now. Sorry this took a while.

Not ideal but whatever, I'm going to rewrite all of this anyway.

Fix unaligned load error on 32-bit architectures

Closes #432

On some 32-bit architectures, 64-bit atomic operations panic when the
value is not aligned properly.

In this package, this causes netConn operations to panic when compiling
with GOARCH=386, since netConn does atomic operations with int64 values
in the netConn struct (namely, with readExpired and writeExpired).

This commit fixes this by moving readExpired and writeExpired to the
beginning of the struct, which makes them properly aligned.

use simd masking for amd64&arm64

See https://github.com/nhooyr/websocket/pull/326#issuecomment-1771138049

Standard library does this too. Unfortunate wish they just exposed it in the
standard library. Perhaps we can isolate the specific code we need later.

I'm just not good enough at assembly. I added tests to confirm that @wdvxdr's
implementation works correctly and matches the output of the basic masking loop.
