Add support for CMD25 to write multiple sequential blocks in one go, in an attempt to speed up uploads. It still needs to be benchmarked if this actually results in a meaningful speedup. Also fix logging from SD driver to be visible even when running under micropython. Signed-off-by: Matthias Blankertz <matthias@blankertz.org>
