`v2.0.3` is incompatible with Angular 11

Describe the bug

From the compatibility table in current README.md file, version 2.0.3 of ngx-device-detector is supposed to be compatible with Angular 11. However, npm (or yarn) throws compatibility warnings when that version of ngx-device-detector is installed in an Angular 11 application.

To Reproduce

Create a sample Angular 11 application - using @angular/cli@11.2.14
```
ng new angular11-test
```
Install v2.0.3 of ngx-device-detector as a production dependency:
```
npm i -E ngx-device-detector@2.0.3
```

Notice the warning:

npm WARN ngx-device-detector@2.0.3 requires a peer of @angular/common@>=7.0.0 <9.0.0 || ^9.0.0-0 ||^10.0.11 but none is installed. You must install peer dependencies yourself.
npm WARN ngx-device-detector@2.0.3 requires a peer of @angular/core@>=7.0.0 <9.0.0 || ^9.0.0-0 || ^10.0.11 but none is installed. You must install peer dependencies yourself.

Expected behavior

Perhaps v2.0.3 of ngx-device-detector was indented to be compatible with Angular 11, but as of right now it is not compatible.
Or perhaps the README.md file has a typo and it should be fixed for folks trying to migrate into Angular 11 in the future.
Maybe a different version of is ngx-device-detector is compatible with Angular 11?

Additional Context

When using yarn as the package manager (instead of npm), the warning message says:

warning " > ngx-device-detector@2.0.3" has incorrect peer dependency "@angular/common@>=7.0.0 <9.0.0 || ^9.0.0-0 ||^10.0.11".
warning " > ngx-device-detector@2.0.3" has incorrect peer dependency "@angular/core@>=7.0.0 <9.0.0 || ^9.0.0-0 || ^10.0.11".
