[TCLCORE] tdbc::sqlite3 with internal dict processing

[Harald O. <har...@el...>]

Its me again, the agent of the Wizards.
2 years ago, I got the task from Wizard Christian to implement the dict 
optimization into tdbc::sqlite3:

https://core.tcl-lang.org/tdbcsqlite3/info/0374f302f59cb71f

Last status was to handle both, arrays and dict, in dependency of the 
sqlite3 version.

This is now implemented.

The implementation is BAD.
I don't know Tcl-OO and already a command

     variable -set {*}{
	-columns -db -needcolumns -resultDict
	-results -sql -Cursor -RowCount -END}

is highly strange and the "variable" documentation does not give any 
idea. Ashoks book helps but it is 100 pages to read to understand this...

So, any help appreciated. Just look to the dump changes and correct them.

Thanks for all,
Harald
