Empty userAgent string doesn't throw an Exception anymore, instead it returns false.

• [bug] No user-agent has been set #946
• added docker-compose.yml with images: setup (composer), runUnitTests, runPerfTests, runLinting, generateModel

Added back implicit $_SERVER scanning for setting the User-Agent string.

• added optional $config to MobileDetect constructor.
• added autoInitOfHttpHeaders configuration which is by default true. This enabled the old behavior from 3.x and 2.x that allows automatic detection of HTTP headers and User Agent from $_SERVER.
• refactored internal CloudFront related methods and the way setHttpHeaders work. It no longer falls back on $_SERVER. The method still calls setUserAgent in case HTTP_USER_AGENT and friends are present.
• added maximumUserAgentLength to the $config, by default the limit is 500.

4.8.01: MobileDetect version with PSR-16 Cache support.

• Support for PHP>=8.x
• PSR-16 cache support https://github.com/php-fig/simple-cache
• Run benchmark tests with https://github.com/phpbench/phpbench
• Split regex strings into array of strings. The main reason for this is future performance improvements, cross-platform compatibility and overall readability.
