Implemented the ability to specify flexible patterns for merging reports

Now it is possible to use wildcards in the `mergeWith` function `?` and `*` and the check has become case-insensitive.

 This will add the reports contents of `release` Android build variant to default reports.
 
+Is it acceptable to use wildcards `*` (zero or several arbitrary characters) and `?` (strictly one arbitrary character).
+The pattern is case-insensitive: `release` and `RelEase` processed the same way.
+
+Examples:
+- add coverage only of release build variant
+```kotlin
+  mergeWith("Release")
+```
+- add coverage of all build variants in the project
+```kotlin
+  mergeWith("*")
+```
+- add coverage of all build variants with build type `release` when there are different flavors
+```kotlin
+  mergeWith("*release")
+```
+
+
 This can be useful if only one command is run in a multimodule project for uniformity, instead of many different ones for each module.
 Or if in a multiplatform project it is necessary to generate a single report for JVM and Android targets.
