talk, talk-llama : pass text_to_speak as a file (whisper/1865)

* talk-llama: pass file instead of arg

it is too hard to quote text in a portable way

* talk-llama: pass heard_ok as a file

* talk-llama: let eleven-labs.py accept options

Options: -v voice, -s savefile, -p (--play)

* talk-llama: check installed commands in "speak"

Pass "-q" to eleven-labs.py to skip checking whether elevenlabs is installed

* talk-llama: pass voice_id again

in order to sync talk with talk-llama

* talk: sync with talk-llama

Passing text_to_speak as a file is safer and more portable
cf. https://stackoverflow.com/a/59036879/45375

* talk and talk-llama: get all installed voices in speak.ps1

* talk and talk-llama: get voices from api

* talk and talk-llama: add more options to eleven-labs.py

and remove DEFAULT_VOICE because it is deprecated (https://www.reddit.com/r/ElevenLabs/comments/1830abt/what_happened_to_bella/)

```
usage: eleven-labs.py [-q] [-l] [-h] [-n NAME | -v NUMBER] [-f KEY=VAL] [-s FILE | -p] [TEXTFILE]

options:
  -q, --quick           skip checking the required library

action:
  TEXTFILE              read the text file (default: stdin)
  -l, --list            show the list of voices and exit
  -h, --help            show this help and exit

voice selection:
  -n NAME, --name NAME  get a voice object by name (default: Arnold)
  -v NUMBER, --voice NUMBER
                        get a voice object by number (see --list)
  -f KEY=VAL, --filter KEY=VAL
                        filter voices by labels (default: "use case=narration")
                        this option can be used multiple times
                        filtering will be disabled if the first -f has no "=" (e.g. -f "any")

output:
  -s FILE, --save FILE  save the TTS to a file (default: audio.mp3)
  -p, --play            play the TTS with ffplay
```

* examples: add speak_with_file()

as suggested in the review

* talk and talk-llama: ignore to_speak.txt
