#### New `splat` behavior

Previously `splat` would have added a `meta` property for any additional
`info[SPLAT]` beyond the expected number of tokens.

**As of `logform@2.0.0`,** `format.splat` assumes additional splat paramters
(aka "metas") are objects and merges enumerable properties into the `info`.
e.g.

``` js
const { format } = require('logform');
const { splat } = format;
const { MESSAGE, LEVEL, SPLAT } = require('triple-beam');

console.log(
  // Expects two tokens, but three splat parameters provided.
  splat().transform({
    level: 'info',
    message: 'Let us %s for %j',
    [LEVEL]: 'info',
    [MESSAGE]: 'Let us %s for %j',
    [SPLAT]: ['objects', { label: 'sure' }, { thisIsMeta: 'wut' }]
  })
);

// logform@1.x behavior:
// Added "meta" property.
//
// { level: 'info',
//   message: 'Let us objects for {"label":"sure"}',
//   meta: { thisIsMeta: 'wut' },
//   [Symbol(level)]: 'info',
//   [Symbol(message)]: 'Let us %s for %j',
//   [Symbol(splat)]: [ 'objects', { label: 'sure' } ] }

// logform@2.x behavior:
// Enumerable properties assigned into `info`.
//
// { level: 'info',
//   message: 'Let us objects for {"label":"sure"}',
//   thisIsMeta: 'wut',
//   [Symbol(level)]: 'info',
//   [Symbol(message)]: 'Let us %s for %j',
//   [Symbol(splat)]: [ 'objects', { label: 'sure' } ] }
```

The reason for this change is to be consistent with how `winston` itself
handles `meta` objects in its variable-arity conventions.

**BE ADVISED** previous "metas" that _were not objects_ will very likely lead
to odd behavior. e.g.

``` js
const { format } = require('logform');
const { splat } = format;
const { MESSAGE, LEVEL, SPLAT } = require('triple-beam');

console.log(
  // Expects two tokens, but three splat parameters provided.
  splat().transform({
    level: 'info',
    message: 'Let us %s for %j',
    [LEVEL]: 'info',
    [MESSAGE]: 'Let us %s for %j',
    // !!NOTICE!! Additional parameters are a string and an Array
    [SPLAT]: ['objects', { label: 'sure' }, 'lol', ['ok', 'why']]
  })
);

// logform@1.x behavior:
// Added "meta" property.
//
// { level: 'info',
//   message: 'Let us objects for {"label":"sure"}',
//   meta: ['lol', ['ok', 'why']],
//   [Symbol(level)]: 'info',
//   [Symbol(message)]: 'Let us %s for %j',
//   [Symbol(splat)]: [ 'objects', { label: 'sure' } ] }

// logform@2.x behavior: Enumerable properties assigned into `info`.
// **Strings and Arrays only have NUMERIC enumerable properties!**
//
// { '0': 'ok',
//   '1': 'why',
//   '2': 'l',
//   level: 'info',
//   message: 'Let us objects for {"label":"sure"}',
//   [Symbol(level)]: 'info',
//   [Symbol(message)]: 'Let us %s for %j',
//   [Symbol(splat)]: [ 'objects', { label: 'sure' } ] }
```
