strm2oas --compression-level=10 doesn't write rep 1/2/3

[stefanottili]

The attached test.gds.gz contains 6 rectangles placed as a 3x2 array with 100x75 spacing.
This could be written as a rep 1, but strm2oas doesn't do that, no matter the compression-level.
Isn't it supposed to be doing that even at the default compression level of 2 ?

Since zlib compresses larger rep 11 very well, rep 1/2/3 will only lead to small file size reductions.

rep 11 4 25 (4,0) (4,0) (-8,3) (4,0) (4,0)
rep 1 1 0 100 75
