Big fan of this! Working with a 16KB box for the Exa shuffle was a bit of a pain, having to iterate 4KB chunks and do careful arithmetic. Doable, but tedious and kind of unnecessary. |

Changes and tests look good to me, just one small docs question
These opcodes simplify working with large boxes. There are simple combinations of existing codes to do the equivalent on boxes smaller than 4k. But they require moving box content into AVM values that cannot exceed 4k. So, for big boxes it is useful to have these operations. (box_splice may also be a nice convenience, even for small boxes)

Both opcodes seem convenient, but not quite necessary, for smaller boxes.
