feat: Add support for custom relay files

Previously, the only way to specify relays for import and blastr was to list them directly in the .env file. This commit introduces the ability to specify a file path for the relays instead. Two example JSON files have been added to the .gitignore, and instructions for using them have been added to the README. This feature provides a more flexible and scalable way to manage relays.

 Open the `.env` file and set the necessary environment variables.
 
+If you want to use custom relay files for import and blastr, you can specify IMPORT_SEED_RELAYS_FILE and BLASTR_RELAYS_FILE in the .env file. First, copy the example JSON files:
+   
+```bash
+cp import_seed_relays.example.json import_seed_relays.json
+cp blastr_relays.example.json blastr_relays.json
+```
+
+Then, set the paths to the files in the .env file:
+
+```bash
+IMPORT_SEED_RELAYS_FILE=import_seed_relays.json
+BLASTR_RELAYS_FILE=blastr_relays.json
+```
+
+The JSON should contain an array of relay URLs (without ws:// or wss://):
+
+```json
+[
+  "relay.damus.io",
+  "nos.lol",
+]
+```
+
 ### 4. Build the project
