TypeScript rewrite (#6)

Maintains the same signature and tests, just rewriting using TypeScript, as well as using [tsdx](https://github.com/jaredpalmer/tsdx) for modern asset generation.

The goal is to be compatible with [unpkg](https://unpkg.com) and [Pika](https://www.pika.dev).

 ### Date object notation
 
 Every returned day or date argument follows this notation:
+
 ```js
 {
-    day: 14,
-    month: 9,
-    year: 1986,
-    weekDay: 4,
-    selected: false,
-    siblingMonth: false,
-    weekNumber: 42
+  day: 14,
+  month: 9,
+  year: 1986,
+  weekDay: 4,
+  selected: false,
+  siblingMonth: false,
+  weekNumber: 42
 }
 ```
 
-Properties `month` and `weekDay` respect JavaScript’s [`Date.prototype`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/prototype).
-
-Only `day`, `month`, and `year` are necessary as input parameters for methods that require a date.
