[fidlcat] decode traces

With the option --from=trace, fidlcat is able to read a program trace
and replace all the syscall dumps by their decoded version.

For example:
Attempting to connect to the daemon. This may take a couple seconds...
syscall 0x7ffc90bd25b8 channel_create 1623951365995328698 2821426 2821426 1 2 0
syscall 0x7ffc90bd2bb0 startup 2821426 2821426 Channel(1) dir /svc
syscall 0x7ffc90bd3bd8 channel_create 1623951365995367083 2821426 2821426 9 a 0
syscall 0x55fdf4fdb750 channel_write_etc 1623951365995377909 2821426 2821426 1 24 1
syscall 0x55fdf4fdb750 write_bytes 00 00 00 00 00 00 00 01 ab 89 f9 f2 d9 06 68 55 ff ff ff ff 00 00 00 00
syscall 0x55fdf4fdb750 write_etc_handle 0 0000000a 0000000e 4 0
syscall 0x55fdf4fdb750 write_status 1623951365995394610 0

Will be replaced by:
Attempting to connect to the daemon. This may take a couple seconds...
