Change target binary library name and copy header

* methods get_model_by_name, get_model_by_lang, get_model were added into the model class

* importing modules changed to using components; introduced constant MODELS_HOME_DIR; simplified code

* added new model folders into init; changed samples and transcriber bin for new mode loader

* changed back in cli.py lang arg to args.lang

* added 3 directories instead of 1 to check for models

* cli.py: added 3 args instead of 1 for model; __init__.py: changed script get_model_path for run get_model_by_name/lang inside current directory

* deleted default env var

* cli.py: changed arg_name; __init__.py: changed const name, changed model loading only for last directory

* deleted unused method

* changed by_name, by_lang methods, added download_model method

* deleted env variable initialization

* deleted print()

* deteled unused modules

* added progress_bar, added folder AppData/Local/vosk for model search

* changed download_model methond; added my_hook method

-# Maintenance
-
-To maintain this module, please ensure the following.
-1. Kotlin version is kept up to date.
-This will be found in the plugins block of the [build.gradle.kts](./build.gradle.kts).
-Ensure both multiplatform and serialization have the same value.
-2. Ensure dependencies are up to date
-3. Ensure that the android min & target sdks are up to date.

-# vosk-api-kotlin
-
-The vosk-api wrapped using Kotlin Multiplatform.
-
-## Usage
-
-The following are ways to use this wrapper.
-
-### JVM
-
-For Java & Android targets.
-
-```kotlin
-dependencoes {
-    val voskVersion = "0.4.0-alpha0"
-
-    // Generic
-    implementation("com.alphacephei:vosk-api-kotlin:$voskVersion")
-
-    // Android
-    implementation("com.alphacephei:vosk-api-kotlin-android:$voskVersion")
-}
-```
-
-## Building
-
-To build this project, follow the following steps.
-
-1. Install `libvosk`.
-This can be done from [source][source install] (parent monorepo) 
-or [downloaded][download].
-2. Download a [Vosk model](https://alphacephei.com/vosk/models) to use.
-  - It is suggested to use a small model to speed up tests.
-3. Once both are downloaded and placed into a proper location (hopefully following UNIX specification).
-Set the following environment variables:
-  - `VOSK_MODEL` to the path of the model.
-  - `VOSK_PATH` to the path of `libvosk`.
-These are used by the various tests to operate.
-4. Now that the required steps are complete, one can run `./gradlew build`.
-
-## Kotlin/Native
-
-Currently, the native target is disabled due to a lack of vosk-api packaging on platforms.
-Further worsened by the fact that installing the vosk-api on Linux systems is a chore.
-
-First, either install from [source][source install]
-or [download][download] and install into the proper unix directories as expected in
-[libvosk.def](./src/nativeInterop/cinterop/libvosk.def).
-
-To enable development for Kotlin/Native, do either for the following.
-- Add `NATIVE_EXPERIMENT=true` to your environment.
-- Go into [build.gradle.kts](./build.gradle.kts) & find `enableNative` & set the right side to true.
-
-Afterwards, when syncing the project, the native source sets will become available to work on.
-It is suggested to run `cinteropLibvoskNative` to generate the Kotlin C bindings to work with.
-
-## Future
-
-- Possibly target Kotlin/JS
-- Possibly target Kotlin/Objective-C (?)
