Implemented paging in browse feature of music providers

[robsonke]

• frontend pr is coming up
• let me know if this is an oke way to limit the results, especially in the specific providers overriding the browse method
• I've tested the radiobrowser option, I dont have local files or an audiobookshelf option

As discussed in discord, this is not going to work due to the fact you will completely loose sorting this way.
If you want to return multi-thousand items listings in browse, the only way is to split them up in sublevels.
