Problem: arrays with readUntil: "eof" or lengthInBytes loop until offset reaches the end. If an element consumes 0 bytes (e.g. the element is only a pointer, or a seek driven by input data), offset never advances and the loop runs forever while the array grows until OOM.

Repro (hangs):

new Parser()
  .array("a", { type: new Parser().pointer("p", { offset: 0, type: "uint8" }), readUntil: "eof" })
  .parse(Buffer.from([1]));

Fix: for these two loop forms, record offset at the start of each iteration and throw Array element did not consume any bytes if it did not advance. Fixed-length and readUntil-function arrays are unchanged. Added a regression test covering both forms.
