[BINCODE] assertion when using a binary/read command without providing the required additional value

[Oldes]

For example such a code:

binary/read #{010203} [SKIP] ;; without providing number of bytes!

Throws an error:

** Access error: invalid spec or options: #(end)
** Where: binary
** Near: binary/read b 'skip

Since the internal value #(end) is used in the error message, it is asserted in the GC pass as System Error #1206.

The error message in such a case must be:

** Access error: invalid spec or options: SKIP
