description: >
Enable "compression" of arbitrary data pointers into an unsigned 16-bit
value. Use together with DUK_USE_DATAPTR_ENC16 and DUK_USE_DATAPTR_DEC16.
Pointers compressed are any void pointers in C code, not just the Duktape
heap. Also NULL pointer must encode and decode correctly.
Currently it is required that NULL encodes to integer 0, and integer
0 decodes to NULL. No other pointer can be encoded to 0.
NOTE: This feature option is currently unimplemented, i.e. Duktape won't
compress any data pointers at the moment.
