Added CLI crate for stubs, installation and removal (#107)

* started work on stub generator

* Worked on stub CLI tool

* Unused import

* Account for namespaces in function and class names

* Add support for docblocks on structs

* Push Rust comments to stubs

* Add indentation to stub generation

* Add CLI application to install and generate stubs

This time CLI application is defined on user side, called with `cargo
run -- ..args..`

* Export anyhow result

* Add constants to stub file

* Removed stub symbols

No longer required as we are now building while also linking to PHP.
Keeping the stubs causes the stubs to override the real symbols in the
extension.

* Fix stubs for real this time

Removed stub symbols as they were being included in the extension
dylib, fix by loading the PHP executable as a dylib, loading the
required symbols globally.

* Maybe actually fix stubs this time

* Forgot to remove PHP binary loading

* let's give this another go... cargo subcommand

Now called via `cargo php <install,stubs>`.

* Added `remove` command

* Tidied up cargo-php, commented, set up CI

* Fix return types with non-ident types

* define namespace ordering

* Fix tests, replace `Self` when in outer context

* Moved allowed bindings into separate file

* Update guide with CLI instructions

+// This is a cheeky hack - since we need the list of allowed bindings in both
