Small fix on some examples

[Edduaardo]

Describe the bug
In some examples, when declaring a SH1106 display some examples are using SH1106 instead of SH1106Wire class and recommending to import the SH1106Wire.h header, and since the SH1106 class doesn't exist on SH1106Wire.h header, it errors out. Since the recommended is the SH1106Wire now I created a branch with the fix on the examples.
