clock_dual.py, fixed up the manifest]

The 2-bit RLE encoding, in addition to supporting colour is also fully
ROMable meaning we can save 32 bytes of RAM per image by switching to
2-bit encoding.

Switch everything in icons and font.clock over to 2-bit encoding.

Note: this requires all the clock PNG files to be reencoded (because
      they were originally in 1-bit grayscale format and this is no
      longer supported by the encoder).

This reduces RAM overhead by 480 bytes and has only a negligable effect
on FLASH usage (+4 bytes).

At 36pt this is already gobbling a fair bit of flash so, for now, we've
restricted this only numerals (and colon).

This is a useful but modest optimization (maybe 3% in string
rendering.
