[Core] Do not use %pos% to get the current position of the player

[LucBerge]

Is your feature request related to a problem? Please describe.
When a program begins, the player position need to be retrieved for transportation API (to know where to go). It is currently done by doing %pos% in the chat. When the general channel is not displayed, it's impossible to get the position back. Because of this, every program has to have the Channel.GENERAL set in the builder. Moreover, frequently running %pos% is a vulnerability for bot detection.

Describe the solution you'd like
The idea is simply to not use %pos% to get the current position of the player.

Describe alternatives you've considered

• Using OCR to get the position on the top-left hand corner : not always visible and not always readable, rejected.
• Find how other bots do it (Flatybot...etc).
