feat(neuralinterface): function to poll `yaw` and `pitch`

[imjamesb]

There should be functions to get the yaw and pitch of a player using the neural interface.

[jmc529]

These functions can be found within .getMeta___() type functions

for example:

local modules = peripheral.wrap("back")
local meta = modules.getMetaOwner()
local pitch = meta.pitch
local yaw = meta.yaw
