5fc21241d6 hint to the compiler/branch-predictor that 
we expect p to be in bound

if we are suffiently certain that p can never be oob
unsafe get_unchecked could be used to
eliminate bounds checking all together
which should improve performance further.

153f04b72a adjust interrupt handling 
we used to spend ~5.8% of the time on getting the next value of the 0..INSTRUCTIONS_PER_INTERRUPT_POLL iterator

increment on Wrapping<u8> now only takes ~0.58 of the time

8aab887388 switch from Integer to u128 
- u128 is only 16 bytes instead of 24
- incrementing u128 does not involve heap allocations
- u128 should be sufficent
 it would take more than 2 sextilion years to overflow if we would be incrementing it every tick at 5GHz
   i.e. 2^128-1 / 5 GHz / 60 / 60 / 24 / 356 > 2 sextilion

before this ~3.2% of the execution time of the program in https://github.com/mthom/scryer-prolog/issues/3265#issuecomment-4103176469 was spend in the increment_call_count function, after this change it's down to 0.3%

8f39bee463 ISO: Implement the include/1 directive 
Quoting from the standard:

    7.4.2.7 include/1

    If F is an implementation defined ground term designating
    a Prolog text unit, then Prolog text P1 which contains
    a directive include(F) is identical to a Prolog text P2
    obtained by replacing the directive include(F) in P1 by
    the Prolog text denoted by F.

Example:

    :- include("hello.pl").

This addresses #583 and #634.
