15f1320d05 Fix allocate_pstr randomly refusing to properly allocate memory 
This one was a toughie: it turns out that using `ptr::align_of()`` was
a bad idea, since the buffer in `Heap` itself is not aligned to
`Heap::heap_cell_alignment()`, so `ptr::align_of()` would sometimes
return lower values than expected.

That made for an heisenbug: if the alignment of the heap happened to be 4,
then the bug wouldn't trigger.

14c8fc3e34 move ~w to least prominent position, point to more suitable specifiers 
In particular, "~q" is a safe better choice.

3d60094330 ENHANCED: format specifier ~w more faithfully emulates write/1 
In particular, variables now start with "_".

Example:

    ?- format("~w", [X]).
    %@ _A   true.

2d4fcf9714 correct handling of floats with N digits (~f and ~Nf) 
This addresses #2771. Many thanks to @tmerr for reporting the issue!

The code was posted by @UWN in:

    https://github.com/mthom/scryer-prolog/discussions/2805

Many thanks! With additional inputs by @adri326 and @notoria, who also
posted interesting approaches which could help to increase precision
in cases that are currently not ideally handled. Thank you all!

Please see the issue and discussion for more information.
