• I have read and understood the contribution guidelines before making this PR.
• I am aware that this PR may be closed if the above-mentioned criteria are not fulfilled.

Changes Proposed

• Update protocol for login in version 12.91.
• Although the code has been updated to uint16_t , purchases are still limited to 100 items. The change was necessary in this pull request to fix crash when opening the NPC window.
• I will not make/bring the code that brings this increase in quantity, as it is complex and a little big, I will focus only on the protocol part.

for what? If 10.98 doesn't even have the features yet... what's the advantage of advancing a protocol without features?

initial tests for protocol and otb integrity seem to be fine

[omarcopires]

• Everything works as it should, except that it is still not possible to acquire more than 100 NPC items.
• New effects, outfits, depots and mount items have been added.
• New items can be added later.

As soon as this pull is added I will send a new one with the 13x protocol and the basic sound system.
