Get information on a specific parameter passed to a function call.

Expects to be passed the T_STRING stack pointer for the function call.
If passed a T_STRING which is *not* a function call, the behaviour is unreliable.

Will return a array with the start token pointer, end token pointer and the raw value
of the parameter at a specific offset.
If the specified parameter is not found, will return false.

@since 0.11.0

@param int $stackPtr     The position of the function call token.
@param int $param_offset The 1-based index position of the parameter to retrieve.

@return array|false
