Pure JS alternative to pipeline operator, for use until the competing proposals have been settled/TypeScript supports it.

TypeScript and Flow type defs are included with overloads for up to 30 operator functions.

```

import pipeline from '@jcoreio/pipeline'

console.log(

  pipeline(

    '{"foo": "34.567"}',

    JSON.parse,

    x => x.foo,

    parseFloat,

    Math.ceil

  )

)

// prints 35

```

You can use `lodash/flow` for the same purpose, but it doesn't have the same ergonomics as the pipeline operator,

because the input comes at the end instead of the beginning:

```

import flow from 'lodash/flow'

flow(

  JSON.parse,

  x => x.foo,

  parseFloat,

  Math.ceil

)('{"foo": "34.567"}')

```
