Escpos Php Versions Save

This change updates the supported PHP versions, and contains some breaking changes to improve compatibility with newer PHP installs.

Breaking changes to users who are upgrading:

• Support for PHP 7.0. 7.1 and 7.2 has been removed. PHP 7.3 or higher is required from this version.
• Source files now use declare(strict_types=1), which will cause errors for callers which are not using the correct scalar types.

Bug fixes:

• Using the GD library to load images would result in an error on PHP 8. This was due to a change to the GD interface from PHP 8.0.
• The example scripts now refer to vendor/autoload.php, so they will work if this repository is checked out and used standalone.
• PHPUnit has been updated to version 9.0.

Breaking changes for developers who are upgrading:

• Support for PHP 5.x and HHVM has been removed. PHP 7.0 or higher is required from this version.
• The intl PHP extension is now required (see docs). This replaces the use of mbstring and iconv, which are no longer used.
• composer is now required to correctly load dependencies, where it was previously optional.
• Printer::text() will now throw an Exception if invalid UTF-8 is supplied. Use Printer::textRaw() if you are encoding text manually.
• Printer-specific sub-classes of CapabilityProfile have been removed (eg. StarCapabilityProfile). Use a named profile with CapabilityProfile::load() instead.
• The API now uses scalar and return type hinting in some places, which makes it more strict than it was previously.

New features:

• Inclusion of new printer profiles from escpos-printer-db.
• gfx-php has been added as a dependency, which allows image processing to work without gd or imagick being present in most cases.
• A new MultiplePrintConnector has been added, which allows developers to route identical print data to multiple printers simultaneously.

Experimental features:

• A new UnifontPrintBuffer, which uses glyphs from a GNU Unifont hex file as an alternative to the on-board printer fonts. See the included unifont-print-buffer.php example for usage.

Bug fixes:

• Added checks where temporary files are created, to give clearer error messages on setups where the temp directory is misconfigured, see #362

• A RawBT connector and example
