The `suffix_id` is simply an incremental index (see
`ndpi_load_domain_suffixes`), so its value might changes every time we
update the public suffix list.

- ndpi_load_domain_suffixes()
- ndpi_get_host_domain_suffix()
whose goal is to find the domain name of a hostname. Example:
www.bbc.co.uk -> co.uk
mail.apple.com -> com

probabilistic
approach for handling Internet domain names.
For switching back to Aho-Corasick it is necessary to edit
ndpi-typedefs.h and uncomment the line
// #define USE_LEGACY_AHO_CORASICK
[1] With Aho-Corasick
$ ./example/ndpiReader -G ./lists/ -i tests/pcap/ookla.pcap | grep Memory
nDPI Memory statistics:
nDPI Memory (once): 37.34 KB
Flow Memory (per flow): 960 B
Actual Memory: 33.09 MB
Peak Memory: 33.09 MB
[2] With the new algorithm
$ ./example/ndpiReader -G ./lists/ -i tests/pcap/ookla.pcap | grep Memory
nDPI Memory statistics:
nDPI Memory (once): 37.31 KB
Flow Memory (per flow): 960 B
Actual Memory: 7.42 MB
Peak Memory: 7.42 MB
In essence from ~33 MB to ~7 MB
This new algorithm will enable larger lists to be loaded (e.g. top 1M domans
https://s3-us-west-1.amazonaws.com/umbrella-static/index.html)
In ./lists there are file names that are named as <category>_<string>.list
With -G ndpiReader can load all of them at startup
