Change the method of gathering data (WebScrapper -> REST Calls)

[gabuscuv]

HowLongToBeat now uses XHR calls, So, the game data is not already embedded in the page, So It brokes the library.

Using the browser debugger, I noticed some XHR calls to "https://howlongtobeat.com/api/search"
that request data contents:

{"searchType":"games","searchTerms":["Gravity","Rush","2"],"searchPage":1,"size":20,"searchOptions":{"games":{"userId":0,"platform":"","sortCategory":"popular","rangeCategory":"main","rangeTime":{"min":null,"max":null},"gameplay":{"perspective":"","flow":"","genre":""},"rangeYear":{"min":"","max":""},"modifier":""},"users":{"sortCategory":"postcount"},"filter":"","sort":0,"randomizer":0}}

and the answer body contents:

{"color":"blue","title":"","category":"games","count":2,"pageCurrent":1,"pageTotal":1,"pageSize":20,"data":[{"count":2,"game_id":30313,"game_name":"Gravity Rush 2","game_name_date":0,"game_alias":"Gravity Daze 2","game_type":"game","game_image":"Gravity-Rush-2-ms.jpg","comp_lvl_combine":0,"comp_lvl_sp":1,"comp_lvl_co":1,"comp_lvl_mp":1,"comp_lvl_spd":1,"comp_main":71005,"comp_plus":122272,"comp_100":192082,"comp_all":117265,"comp_main_count":114,"comp_plus_count":182,"comp_100_count":72,"comp_all_count":368,"invested_co":0,"invested_mp":0,"invested_co_count":0,"invested_mp_count":0,"count_comp":648,"count_speedrun":0,"count_backlog":1461,"count_review":298,"review_score":77,"count_playing":10,"count_retired":79,"profile_dev":"Project Siren","profile_popular":82,"profile_steam":0,"profile_platform":"PlayStation 4","release_world":2017},{"count":2,"game_id":44680,"game_name":"Gravity Rush 2: The Ark of Time - Raven's Choice","game_name_date":0,"game_alias":"","game_type":"dlc","game_image":"Gravity-Rush-2-ms.jpg","comp_lvl_combine":0,"comp_lvl_sp":1,"comp_lvl_co":0,"comp_lvl_mp":0,"comp_lvl_spd":1,"comp_main":7191,"comp_plus":7987,"comp_100":9483,"comp_all":7807,"comp_main_count":42,"comp_plus_count":19,"comp_100_count":23,"comp_all_count":84,"invested_co":0,"invested_mp":0,"invested_co_count":0,"invested_mp_count":0,"count_comp":133,"count_speedrun":0,"count_backlog":45,"count_review":67,"review_score":73,"count_playing":0,"count_retired":2,"profile_dev":"Project Siren","profile_popular":9,"profile_steam":0,"profile_platform":"PlayStation 4","release_world":2017}],"displayModifier":null}

This change should be future-proof. (because using a Web Scraper could be an issue if the page changes too much the appearance or the visual representation) and easy to maintain.
I will try to implement it myself.
