feat: increase CosmWasm contract size for default 800kb to 1.6 MB like in Neutron 2.0 release

[dzmitry-lahoda]

Problem is that I am trying to add innocent code to cvm contract and get over default limit 819200 bytes. Neutron increased the size in release to 1.6MB (2x)

That makes code to be 824K which is over limit.

As you can see not a lot of changes. I observer than sometimes removing code, like some dependency may increase size of wasm. So hardly predictable.

Improvement blocked by:

• Astroport/Osmosis - they depend on tenderint-rs
• ibc-rs, also I use only app types, they use tenderimnt-rs time, may be of different version
• still on forks, leading to duplication of code

So cannot fix fast.
