Use less bits for wire_ports net

[wrefgtzweve]

Uses 13 bits instead of 16 for networking the entity in wire_ports.
Which is fine as gmod can't have that many entities in the first place, base gmod also uses 13 for net.WriteEntity() https://github.com/Facepunch/garrysmod/blob/master/garrysmod/lua/includes/extensions/net.lua#L5

I'm guessing it's not possible to change to WriteEntity for this task?

[wrefgtzweve]

Seemed like all the logic is using actual entity ids rather than entities

The entity limit could increase again in the future so I'm not really a fan of this.

[storm37000]

using Write/ReadEntity should grow with the entity limit when and if it is increased.

[wrefgtzweve]

I can make a local var for it but yeah i can see the issue, however currently networking useless bits isn't great either.
Would be really hacky but grabbing this upvalue could be a possibility but i doubt anyone would want that. Ideally it'd have just been globally available.

My suggestion, make a request to have that exposed globally and for now just have 13 in an equally named upvalue until it becomes global.

Entity limits don't just increase overnight. We'll have plenty of forewarning to change it as necessary until the value gets exposed.
