Color format not changing

[AndreoBotelho]

I've lost a lot of time figuring out why my display was not working with you library, every thing was working but color format didn't change to 16 bits so image was messed but finally I find out that in your init function was missing a soft reset, to fix it just a the line

ST7789_WriteCommand(ST7789_SWRESET);"

just after the hard reset.
