[gdal-dev] Enabling default compression for COG ?

I think it’s reasonable to have a default compression. In rio-cogeo I’ve set the default to `DEFLATE` but that’s was a personal preference.

I've heard people "complaining" about that, or people just not realizing that specifying a compression method was something reasonable to do. Likely a lossless one to be conservative. ZSTD is probably not reasonable as it's too non-standard outside of the GDAL/libtiff world. So the choice would go basically between LZW or DEFLATE. LZW has probably the best compatibility profile (but the less efficient). I guess that most browser based solutions would handle it ? Thoughts ?
