Remove ImmutableByteArray.chunked and its only user

[phcoder]

In its current form we would just get infinite recursion. It's not actually
ever called. Kill it and its only user

Ah, I have a TODO for this:

metrodroid/src/commonMain/kotlin/au/id/micolous/metrodroid/card/felica/FelicaReader.kt

Lines 207 to 216 in f53978b

	// TODO: Request more than 1 block
	var addr = 0
	var result = fp.readWithoutEncryption(systemNumber, serviceCode, addr)
	while (result != null) {
	blocks += FelicaBlock(result)
	addr++
	if (addr >= 0x20 && liteMagic)
	break
	result = fp.readWithoutEncryption(systemNumber, serviceCode, addr)
	}

Unfortunately there's no documented way to probe the card how big a Service is, so I think the only option is to hard code it and hope for the best.

I've got another commit which should fix the looping issue, and fetches multiple blocks at a time. It improves performance a fair bit too
