Attempting to save a game fails because the F_WRITE syscall is not implemented.

Load SAVE disk then enter file name.
(default file name is ZORK1.SAV).
Type <ENTER> to continue  > foo

{"time":"2024-04-15T22:11:34.391482519+03:00","level":"ERROR","msg":"Unimplemented syscall","syscall":21,"syscallHex":"0x15"}
Error running ZORK1.COM: UNIMPLEMENTED

The file is created, after the disks were reset (implemented in #20).

Implement F-WRITE
177425a 
This pull-request implements (sequential) file writing operations,
which allow Zork to save its game-state.  I've not yet implemented
F-READ (which is tracked in #22) but confirmed the save loads in
another emulator.

This closes #21:

```
>inventory
You are carrying:
  A glass bottle
  The glass bottle contains:
    A quantity of water
  A leaflet

>look
Kitchen
You are in the kitchen of the white house. A table seems to
have been used recently for the preparation of food. A passage
leads to the west and a dark staircase can be seen leading
upward. A dark chimney leads down and to the east is a small
window which is open.
On the table is an elongated brown sack, smelling of hot
peppers.

>save
Load SAVE disk then enter file name.
(default file name is ZORK1.SAV).
Type <ENTER> to continue  > FOO

Load Game Disk if it was removed.
Type <ENTER> to continue >

Ok.

>quit
Your score is 10 (total of 350 points), in 18 moves.
This gives you the rank of Beginner.
Do you wish to leave the game? (Y is affirmative): >y
