Improve CSV data provided to researchers about lookit-api HOT 2 CLOSED

Plan, with many thanks to @jchu10:

Provide download of 4 separate files:

• Session summary CSV: has headers

response_id
response_uuid
response_sequence.[N]
response_conditions.[N].[frameName, each key flattened]
response_completed
response_withdrawn
response_consent_ruling
response_consent_arbiter
response_consent_time
response_consent_comment
study_id
study_uuid
participant_id
participant_uuid
participant_nickname
child_id
child_uuid
child_name
child_birthday
child_gender
child_age_at_birth
child_additional_information

• Session summary CSV data dictionary, filled in, since above headers are standard

• Session data CSV, longer format: breaks down response_global_event_timings and response_exp_data. Has headers

response_uuid
frame_id (e.g. 5-mood-survey OR global for events in response_global_event_timings)
key (e.g. formData.happy OR event.0.name, event.0.timestamp, etc.)
value (e.g. 6)

• Session data CSV data dictionary, partially prepopulated. Show all unique frameID - key pairs and provide space for researcher to give explanation of that value's meaning (e.g., 5-mood-survey / formData.happy: this is how happy the participant is on a scale from 1 to 7, blank means they skipped the question)

Here's what the download data page looks like now:
