[FR] Detail unvalidated text corpus status

[HarikalarKutusu]

Is your feature request related to a problem? Please describe.
In the first iteration of the text-corpora release in v17.0, the status of sentences are not clear. AFAIK, there are 4 states for a sentence:

1. Added - not yet validated (=> Needed for community planning)
2. Added - Invalidated ( => One can revisit these sentences and correct the mistakes and repost.)
3. Added - Validated => Can be recorded (maybe already recorded)
4. Added - Validated => (Possibly Recorded) => Disabled (=> one may like to remove these from voice corpus to get better quality)

• 1 & 2 are in unvalidated_sentences.tsv file, but we have no way of distinguishing them
• 3 & 4 are in validated_sentences.tsv file, from clips_count column we can find if they are recorded (if >0), and from is_used field we can see if they are later disabled (if = 0)

During an analysis we need to distinguish all states, but we cannot get these:

• How many sentences are waiting to be validated
• How many sentences are invalidated

Describe the solution you'd like
IMO, the easiest way to do this is to add up/down vote count fields to the unvalidated_sentences.tsv file

Describe alternatives you've considered
One could also use invalidated_sentences.tsv and other_sentences.tsv files to distinguish, like it is done for voice-corpora, but former method would be better as it will have more data for analysis and will result in less files.
