More than four kans can be declared

[swaq]

I was able to declare seven kans (between extended and called kans). Seven dora indicators were flipped over, past the end of the dead wall, the last one disappearing on the second to last draw.

There should never be more than four kans declared at any one time, at least according to the EMA rules:
"If no-one wins on the discard after the fourth kong, the hand ends in abortive draw,
except in the case where it’s same player who has all four kongs, in which case playing
continues, but no further kongs may be declared."
