feat(indicator): add `<SIndicator>` component

[kiaking]

I've changed props a bit from the issue.

<SIndicator state="running" />

interface Props {
  size?: Size
  state: State
  mode?: Mode
}

type Size =
  | 'nano'
  | 'mini'
  | 'small'
  | 'medium'
  | 'large'
  | 'jumbo'

type State =
  | 'pending'
  | 'ready'
  | 'queued'
  | 'running'
  | 'completed'
  | 'failed'

type Mode =
  | 'colored'
  | 'monochrome'
