Feature Request: narrow any types in typescript files

[DanKaplanSES]

console-table-printer/src/models/external-table.ts

Lines 16 to 22 in c51f8d9

	export interface ComputedColumn extends ColumnOptionsRaw {
	function: (arg0: any) => any;
	}
	export type RowSortFunction = (row1: any, row2: any) => number;
	export type RowFilterFunction = (row: any) => Boolean;

These type signatures use any unnecessarily. They could be narrowed to more useful types. I could submit a PR, but I'd like to understand the reason for this first; this may be working as intended.
