Can the text size change?

[ElRobotaBiomedico]

Hello, first of all, thank you very much for the contribution, it is very appreciated. I only have a small doubt, is there any function that allows you to change the size of the text?

I'm interested in changing the text size for a project in which I work

Same as above, would be nice to include text sizes

The chip supports double size text natively but command to do so is not in this driver.
For my project I added a method to do this.

def zoom(self):
        '''
        Set OLED to display double size
        '''
        self.temp[0] = 0x00
        self.temp[1] = 0xD6
        self.i2c.writeto(self.addr, self.temp)
        self.temp[1] = 0x01
        self.i2c.writeto(self.addr, self.temp)

The setting is retained by the display over reboots so an unzoom command is also needed.

I've done a PR on the upstream micropython-lib repo.
