Add a script to get subscribed and onboarded laconicd accounts (#22)

Part of [laconicd testnet validator enrollment](#19)

The script:
- Fetches onboarded participants using the configured laconicd GQL endpoint
- Reads a given CSV file with subscribers data
- Fetches all the onboarding txs using given laconicd RPC endpoint
- For each subscriber registered as a participant, maps the laconic pubkey and latest onboarding tx height
- Outputs the result in a CSV

+## Prerequisites
+
+- NodeJS >= `v18.17.x`
+
+## Instructions
+
+- Change to scripts dir:
+
+  ```bash
+  cd scripts
+  ```
+
+- Install dependencies and build:
+
+  ```bash
+  yarn && yarn build
+  ```
+
+- Create required env configuration:
+
+  ```bash
+  # Update the values as required
+  # By default, live laconicd testnet (laconicd.laconic.com) endpoint is configured
+  cp .env.example .env
+  ```
+
+- Map subscribers to onboarded participants:
+
+  ```bash
+  yarn map-subscribers-to-participants --subscribers-csv <subscribers-csv-file> --output <output-csv-file>
+
+  # Example:
+  # yarn map-subscribers-to-participants --subscribers-csv subscribers.csv --output result-$(date +"%Y-%m-%d%Y%m%d").csv
