Update installation method to NOT require 'go get'

[phu54321]

While following the instruction, I get this.

(base)  ~/Desktop/ go get github.com/zach-klippenstein/adbfs
go: go.mod file not found in current directory or any parent directory.
	'go get' is no longer supported outside a module.
	To build and install a command, use 'go install' with a version,
	like 'go install example.com/cmd@latest'
	For more information, see https://golang.org/doc/go-get-install-deprecation
	or run 'go help get' or 'go help install'.

Instruction should be fixed. Thanks.

There's a fork that is compiling for me. https://github.com/exidler/adbfs

You'll also need https://github.com/exidler/goadb located side-by-side with this checkout.

(Go's project management is the most esoteric annoying piece of shit to an outsider. ./cmd/adbfs/...? What is shit anyways? Cannot stand it, so annoying. It feels like lots has changed in go too; go added modules but broke everything that worked? Also this package uses go-deps, which has been gone for 3 years now.)
