Silly semeai reading with double-ko

Description

In the attached position, deep_semeai_reading.sgf, the semeai reading produces a non-sensical reading once one of the two groups can only be killed by filling in one of two kos.

This leads to an assertion failure when compiling with MAX_BOARD = 9 due to running out of MAX_STRINGS, but thats a little besides the point.

deep_semeai_reading-2.sgf shows the variation that leads to a crash.
