Rewrite transformations logic from TypeScript

[Rulexec]

There is a bunch of transforms written in ts — https://github.com/anfivewer/an5wer/tree/a8b65caf14b2d7f0846143e060774266c3b41edc/packages-diffbelt/util/src/transform

We need to port them to Rust in three variants:

• With direct calls to collection methods

• With async calls via remote interface (currently http)

• Compilable to wasm for usage from nodejs, it should receive options of transform (initial/intermediate/target collection, params), return list of required api-calls, data for client processing, then receive responses/calculated data and repeat

• MapFilter

• Aggregate: Init

• Aggregate: Map

• Aggregate: Get target record

• Aggregate: Create target info

• Aggregate: Create initial accumulator

• Aggregate: Reduce

• Aggregate: Merge accumulators

• Aggregate: Apply

• Aggregate: Finalize

• Unique count complex transform

• Percentiles complex transform
