Composer support

[ngugijames]

Hey,

It is not possible to load this package via composer at the moment because

1. The package is not available via packagist
2. The composer file does not define the package name.

hi @ngugijames I have made a fork and made it available https://packagist.org/packages/gelinger777/escpos-tools
but it has to still bit changed as it uses a lot std_error as output. so mainly it can be used now in simple command line tools. Keep your eye on releases. I plan to rework it a bit.
