Version 6

Few changes where introduce in version 6 in order to standardize the library and support Angular 9. The following steps should be considered when migrating from version 5.

1. When importing the module do not use .forRoot(); In WebStorm, replace in path:

- SystelabMetersModule.forRoot\(\)
- SystelabMetersModule

2. When importing services and modules import them from systelab-meters root. In WebStorm, replace in path:

- from 'systelab-meters/lib.+
- from 'systelab-meters';
