FormatCache
The FormatCache caches the calculations needed to determine the correct format for a specific serializable tree. There are 3 options provided by default:
Dummy This is a cache that doesn't actually cache, it disables caching
DefaultFormatCache This is a simple cache that does not use any locking enabling thread safety
defaultSharedFormatCache This function will provide wrapper for the default cache that uses threadLocals for native/jvm/android to provide thread safety (at the cost of performance). Note that the native implementation is not particularly in the case of individual formats.
