## Motivation `LdConst` currently deserializes the BCS encoded constants on every invocation. This is unnecessary and also makes it considerably slower than `Ld*` of same data size. This PR uses...
LdConst deserializes constants from BCS every-time we hit LdConstSee [here](https://github.com/move-language/move/blob/main/language/move-vm/runtime/src/interpreter.rs#L806). Seems wasteful. We should keep a pool/lookup-table of already deserialized constants either in the resolver [here](https://github.com/move-language/move/blob/main/language/move-vm/runtime/src/interpreter.rs#L800) or somewhere else.

Opening and using DBMaps require lots of boilerplate code. [Example](https://github.com/MystenLabs/sui/blob/main/crates/sui-core/src/authority/authority_store_tables.rs) Other features like dump also need to be hand written and maintained. See https://github.com/MystenLabs/mysten-infra/issues/104
For debugging, we want to be able to dump any db table We currently have this for validator and gateway dbs, but want it for others
This avoids blowing up resources
* Introduces `#[derive(DBMapUtils)]` which reduces boilerplate code for opening DBMaps and dumping tables. * Supports DB options as attributes. Example `#[options(optimization = "point_lookup", cache_capacity = 1000000)]` * Added derive macro...
