docs/commands: add from.md, update subcommands (#1712) 
This adds a top-level document for the new `from` command, with a list of links of all the subcommands.

All the from-* subcommands keep their filename, but the content is updated to use the new subcommand syntax.

Needs matching update for to*

from ics

Parse text as .ics and create table.

Syntax: from ics

Examples

Suppose calendar.txt is a text file that is formatted like a .ics (iCal) file:

> open calendar.txt
BEGIN:VCALENDAR
BEGIN:VEVENT
DTSTART:20171007T200000Z
DTEND:20171007T233000Z
DTSTAMP:20200319T182138Z
SUMMARY:Basketball Game
UID:4l80f6dcovnriq38g57g07btid@google.com
...

Pass the output of the open command to from ics to get a correctly formatted table:

> open calendar.txt | from ics
───┬────────────────┬──────────────────┬────────────────┬────────────────┬────────────────┬────────────────┬────────────────
 # │ properties     │ events           │ alarms         │ to-Dos         │ journals       │ free-busys     │ timezones
───┼────────────────┼──────────────────┼────────────────┼────────────────┼────────────────┼────────────────┼────────────────
 0 │ [table 0 rows] │ [table 1 row]    │ [table 0 rows] │ [table 0 rows] │ [table 0 rows] │ [table 0 rows] │ [table 0 rows]
───┴────────────────┴──────────────────┴────────────────┴────────────────┴────────────────┴────────────────┴────────────────

> open calendar.txt | from ics | get events | get properties | where name == "SUMMARY"
─────┬─────────┬───────────────────────────────────────┬────────
 #   │ name    │ value                                 │ params
─────┼─────────┼───────────────────────────────────────┼────────
   0 │ SUMMARY │ Basketball Game                       │
