blacklist is not work for TOTALCMD64.exe

[Tback1]

# List of hotkey conflict apps
# e.g. game1.exe,game2.exe
blacklist = TOTALCMD64.exe,TOTALCMD.exe,foobar2000.exe

could block the foobar2000. but not work for the Totalcmd, I tried only one item blacklist = TOTALCMD64.exe also no effect OR put different place blacklist = foobar2000.exe,TOTALCMD64.exe,TOTALCMD.exe

I watch the source code find this: https://github.com/sigoden/window-switcher/blob/33f311603b483fa7d70bc950bec4dd669af1d2f3/src/config.rs#L87

the filename is Uppercase but to_lowercase() make this issue so it not fit for all software, Especially the name use camel cased.
