Add static analyse like phpstan #42
Description
Hello,
i try add static analyse tool phpstan to project and here is output and choise what to do.
Here is commit where are changes https://github.com/h4kuna/GPIO/commit/93fa0c099d61d0a9fb9b2e3eb97032034ecfef8e run it by ./test/phpstan.
1 strict php functions
I will create new class with this php funcions what return two value and make it strictly like this. But here is need only fopen, fwrite and stream_get_contents.
And create own excenption instead of global RuntimeException.

2 php typehint
Here are two way, make it strtly by php typehint or for this moment only by annotation. I'm vote for first choice and support with php 7.3+, it will be BC break. Here is opended PR #38
