improved lodash

type Func<TArgs extends unknown[], TResult> = (...args: TArgs) => TResult;
/**
 * @description
 * Creates a composite function that invokes the provided functions in sequence from left to right.
 * The first function is called with the initial arguments provided to the new function,
 * and its result is passed as the sole argument to the next function, continuing the chain.
 *
 * As an enhancement over lodash, this implementation provides strong TypeScript type inference
 * for a sequence of up to 7 functions, ensuring type safety through the composition chain.
 *
 * @param {...Function} funcs The sequence of functions to compose.
 * @returns {Function} Returns the new, composed function.
