nix: replace grep and sed with AWK for parsing Gradle deps The mess with regexes is hard to read and think about which is why it had bugs with handling some Gradle formats. It also lowers further the number of dependencies pulled from 785 to 744. Changes: - Added `gradle_parser.awk` script for getting dependencies from Gradle - Changed the `deps.urls` file to contain full URLs to POMs - Dropped the `deps.urls.old` part since `get_urls.sh` no longer exists - Added `CLR` for learing line to `scripts/colors.sh` - Wrote a new `nix/deps/gradle/README.md` - Re-generated `nix/pkgs/go-maven-resolver/deps.nix` Signed-off-by: Jakub Sokołowski <jakub@status.im>

Simply calling `generate.sh` should result in a `deps.json` file which is used in the derivation that provides Gradle dependencies when building the Android app.
You can see in [`nix/mobile/android/release.nix`](../../mobile/android/release.nix) that it's used via the `-Dmaven.repo.local='${deps.gradle}'` Gradle flag.
# Files
First we have the files that store data on Gradle dependencies:
* `proj.list` - List of projects of which our Gradle project consists.
* `deps.list` - List of dependencies for our project and sub-projects.
* `deps.urls` - List of URLs to POMs for all of the dependencies.
* `deps.json` - Final file containing all of the necessary data for Nix.
Generating scripts:
- `generate.sh` - Main script which generates all the above files.
- `get_projects.sh` - Calls Gradle to get a list of sub-projects.
- `get_deps.sh` - Calls Gradle to get all the dependencies of sub-projects.
- `gradle_parser.awk` - An AWK script that parses above Gradle output.
- `url2json.sh` - Converts the list of URLs into a format consumable by Nix.
Finally we have the Nix derivation in `default.nix` which produces a derivation with all of the Gradle project dependencies:
```
$ nix-build --no-out-link --attr pkgs.deps.gradle default.nix
/nix/store/57g95ik19k6gs5w68yid3hzhsax60i3m-status-react-maven-deps
$ ls -l /nix/store/57g95ik19k6gs5w68yid3hzhsax60i3m-status-react-maven-deps | head -n 5

# Dependencies
One dependency these scripts require is the [go-maven-resolver](https://github.com/status-im/go-maven-resolver) which turns a list of packages into list of all URLs of POMs for them and their dependencies.
