updates project to latest AS v4.1.2
- refactors the import of the openCV native libs by importing the dependencies as a git submodule, which also automates this process, so there is no longer the need of copying the native files manually. - passes the path of the openCV native submodule to the CMakeLists.txt. - updates kotlin to the latest version.

## Build Instructions

DocScan makes use of native (C++) OpenCV and OpenCV Java API. The Java part is automatically downloaded after syncing.

### Download native library
14-
For the native part you have to clone this repo:
15-
16-
```shell
17-
git clone https://github.com/hollaus/opencv_libs.git opencv_native
18-
```
19-
### Add native library to the project
20-
Next you have to copy two folders from the native library to the project.
21-
- copy `opencv_native/sdk/native/libs` to `app/src/main/jniLibs`
22-
- copy `opencv_native/sdk/native/jni/include` to `app/src/main/include`
23-
24-
Alternatively, you can create symlinks - as written below. It is assumed that your project root folder (DocScan) and the opencv_native folder are on the same hierarchy level.
