Domain Classification Improvements (#2396)

* Added
size_t ndpi_compress_str(const char * in, size_t len, char * out, size_t bufsize);
size_t ndpi_decompress_str(const char * in, size_t len, char * out, size_t bufsize);

used to compress short strings such as domain names. This code is based on
https://github.com/Ed-von-Schleck/shoco

* Major code rewrite for ndpi_hash and ndpi_domain_classify

* Improvements to make sure custom categories are loaded and enabled

* Fixed string encoding

* Extended SalesForce/Cloudflare domains list
