InsertOrReplaceAll method is not available in this library

I am using SQLite.NET-PCL but as it is now no longer being maintained I want to use this package.
But a very strange thing I found is that, this package does not have InsertOrReplaceAll method which is available in SQLite.NET-PCL

I can not use InsertAll or UpdateAll because, prior to using it, I don't know which records are new and which are existing, considering I have pre-set all primarykey values in the List object.

I have posted this issue and sample code on https://stackoverflow.com/questions/47124476/insertall-updateall-in-sqlite-net-pcl-vs-insertorreplaceall-in-sqlite-net-pcl/

If you have a plan adding this feature in upcoming versions, would be awesome!!
If not, please add this feature if possible. This is a very useful method to Insert or Replace lot of records all at once.

Thanks

Start by reviewing this library's existing InsertAll and UpdateAll behavior, then compare it with SQLite.NET-PCL's InsertOrReplaceAll method and the sample linked in the issue. Done means the package supports inserting or replacing a list when primary keys may identify either new or existing records, with behavior covered by appropriate tests.
