Changes Proposed

Fixes soul balls not being properly displayed in newer clients. (2020+).

2020+ clients split the logic for spirit spheres and soul balls, players may now have both at the same time, and a new packet was introduced for soul balls only (being separated from the spirit spheres one).

Implementation based on rAthena logic/packet. also huge thanks to 4144 for packet dates.

I decided to split clif_spiritball into 2 functions and leave the number of balls to the caller so we can simplify those functions. There were 2 reasons for that:

1. We now have to deal with different packets for each case depending on client
2. Pretty much every call was converting sd/hd to bl, to convert back to sd/hd inside the function... leaving to the caller simplifies things and gives flexibility if someone is looking for some sort of customization

Issues addressed: None, I think (someone mentioned it in discord)
