feat: lexicographical sort order option like `ls` command

[Ju-38]

In eza default sorting is not the same lexicographical order as in ls command.
The default sorting with eza is more like a natural sorting.

Could you develop an option to get lexicographical sorting order? (eza --sort=lg for lexicographical)

A second option to avoid sorting of hidden files first (due to the dot "." in first character) like in ls -a (the first dot is not taken into account for sorting).

Example of ls default sorting

# result of ls 
000.gds
001.gds
100.gds
101.gds
2001.gds
200.gds
201.gds
20A1.gds
