[bug] asset groups/bundles cannot have some chars in names/paths

workaround: in BuildScriptPackedMode.cs - GenerateBuildInputDefinitions(...)

Code (CSharp):

1.                 buildInputDefs.Add(GenerateBuildInputDefinition(assets, groupName + "_assets_" + address)); //**addressables: workaround - removed extension here to remove dots later
2. .........
3.             { //**addressables: workaround for https://issuetracker.unity3d.com/issues/android-gradle-streamingassets-starting-with-an-underscore-not-included-in-builds
4.                 var names = assetsInputDef.assetBundleName.Split('/');
5.                 assetsInputDef.assetBundleName = string.Join("/", names.Select(part => part.TrimStart('_')));
6.             }
7.             { //**addressables: workaround for names with strange chars
8.                 //    fixup for local hosting: bad in bundle names with f.e. %60 (`)
9.                 //    fixup for android build: don't allow single quote (') because of its usage in build.gradle
10.                 //    fixup for cached checking: remove any dots (.) except extension otherwise Caching.IsVersionCached failed
11.                 assetsInputDef.assetBundleName = assetsInputDef.assetBundleName
12.                         .Replace("`", "_")
13.                         .Replace("'", "_")
14.                         .Replace(".", "_")
15.                     ;
16.                 assetsInputDef.assetBundleName += ".bundle";
17.             }
