New ram leak

I get a new ram leak I didn't have before.

It only shows when on cutting edge firmware (2v20.69) and pretokenization is used on upload.

So far I noticed it when fastloading from spotrem to edgeclk .

I have not looked closer on spotrem code yet to see if I could find the leak.

Since fastloading from spotrem is made via fastload utils which we explicitly state is experimental I'm aware this is maybe not a priority. But I think it makes sense to mention the change here at least.

Memory usage increasing when switching between spotrem and edgeclk, both pretokenized:

>reset();

Memory usage increasing a lot when repeatedly fastloading just spotrem and it is pretokenized:

>reset();

Memory usage increasing only slightly (sometimes decreasing) when repeatedly fastloading just spotrem and it's not pretokenized:

>reset();
