Rewrite Kover HTML report

[shanshin]

The current HTML report one is poorly suited for displaying the coverage of code written in Kotlin. It is necessary to think over a new design and implement code to generate a more convenient report.

Suggestions for the layout of the HTML report:

• the report should allow you to browse the coverage in the search mode by packages/classes or directories/files
• only packages or directories of the same level should be displayed on one page, to view child packages/directories, you need to select one of the lines (this may be optional, now all packages are displayed in one large list)
• when opening any file, the coverage should be displayed for all classes in this file (currently only displayed for one class)
• add the possibility of top-level breakdown into subprojects
• if the display of classes from all subprojects is selected, then add a column with the name of the subproject in which this class is declared
