1. test: Add property-based tests …

   Following the discussion started on chaijs#79. I'm opening this PR as an opened question and suggestion to better cover the library and its edge-cases.
   
   First, what is property-based testing?
   
   It's a technic coming from functional world and aiming to help devs into detecting edge cases without having them to think of them too much.
   
   Why, property-based testing?
   
   Well, in order to reduce the risks of bugs and potentially regressions on key libraries.
   
   Could it found problems?
   
   Well, probably. I tried another property but I'm not sure whether or not the failure is considered as ok or not. As such I'm not sure of what to expect from truncate so I was not able to make a decision.
   
   ```js
   it('produces strings with at most <truncate> characters', () => {
     fc.assert(
       fc.property(
         fc.anything({
           withBigInt: true,
           withBoxedValues: true,
           withDate: true,
           withMap: true,
           withNullPrototype: true,
           withObjectString: true,
           withSet: true,
           withSparseArray: true,
           withTypedArray: true,
           withUnicodeString: true,
         }),
         fc.nat(),
         (source, truncate) => {
           const output = inspect(source, { truncate })
           expect(output).to.have.lengthOf.at.most(truncate)
         }
       )
     )
   })
   ```
   
   Who am I?
   
   I'm the author of fast-check, the library added by this PR. It's the leading property-based testing library today.
