Modernize lib

[nikosd23]

package.json — updated dependencies, scripts, and added nyc config:

• log4js ^3.0.4 → ^6.9.1, mocha ^5.2.0 → ^11.3.0, sinon 1.17.7 → ^18.0.0, typescript 2.1.5 → ^4.9.5
• Updated @types/mocha, @types/node, @types/sinon, @types/source-map-support
• Removed istanbul, remap-istanbul, @types/log4js
• Added nyc ^17.1.0
• Replaced istanbul/remap-istanbul test scripts with nyc equivalents

17 test files — sinon.sandbox.create() → sinon.createSandbox()

5 source files — removed async from abstract method declarations (TS4 no longer allows this combination):

• src/lib/processors/aggregator/aggregation-strategy.ts
• src/lib/processors/aggregator/store.ts
• src/lib/processors/processor.ts
• src/lib/processors/throttler/pub-sub.ts
• src/lib/processors/throttler/queue.ts

3 test files — fixed new Promise(r => r()) → new Promise(r => r()) for TS4 strictness

Pull request overview

Modernizes the project’s tooling and TypeScript compatibility by upgrading key dependencies (Mocha/Sinon/TypeScript/Log4js), switching coverage tooling to nyc, and applying the necessary source/test updates to compile and run under the newer toolchain.

Changes:

• Upgraded runtime/dev dependencies (notably log4js, mocha, sinon, typescript) and updated the lockfile to npm lockfile v3.
• Replaced Istanbul/remap-istanbul coverage scripts with nyc and added nyc configuration in package.json.
• Updated tests for Sinon sandbox API changes and TypeScript 4 strictness; adjusted abstract method declarations to remove unsupported abstract async combinations.
