This handler serves reads and writes instantly, without touching the data.
Additionally, the size can be specified. This is useful for performance
testing, as it can be used to remove the overhead of the underlaying I/O
solution.


Installation:

- Copy the correct NOP-Handler file for your system to L:NOP-Handler.
- Copy the NOP DOSDriver definition to SYS:Storage/DOSDrivers/ for
  manual mount or DEVS:DOSDrivers/ if you want it to automount.


Usage:

Specify no name to get an unlimited stream, or a number of Bytes followed by
an optional multiplier to get a stream limited to that size. The following
multipliers are supported:
K = 2^10 = 1024
M = 2^20 = 1048576
G = 2^30 = 1073741824
T = 2^40 = 1099511627776


Examples:

Copy from various sizes to drive:
> copy NOP:1 Work:testfile-1
> copy NOP:123 Work:testfile-123
> copy NOP:1K Work:testfile-1K
> copy NOP:1M Work:testfile-1M
> copy NOP:1G Work:testfile-1G
> list NOHEAD NODATES Work:testfile#?

testfile-1                        1 ----rwed
testfile-1K                    1024 ----rwed

Attempt to fill RAM: by copying from unlimited size:
