react: Move inputs (cells, operations) to input object

[petertseng]

react 1.1.0

As proposed and accepted in #996

indent = false
operations = false

ARGF.each_line { |l|
  if l.include?('version')
    ver = l.split(?")[3]
    ver_components = ver.split(?.).map(&:to_i)
    ver_components[1] += 1
    ver_components[2] = 0
    l[ver] = ver_components.join(?.)
  end

  first_non_space = l.index(/\S/)
  if l.include?('"cells"')
    puts ' ' * first_non_space + '"input": {'
    indent = true
  end
  operations ||= l.include?('"operations"')
  l.delete!(?,) if operations && l.strip == '],'
  puts "#{'  ' if indent}#{l}"
  if operations && l.strip == ?]
    puts ' ' * first_non_space + '},'
    operations = false
    indent = false
  end
}

also note the additional commit that adds "expected": {}, since it's required but we expect nothing other than what was already expected in operations.

In its current state, it is not possible to consistently place expect_cell_value in expected, so I do not.

[petertseng]

Note that this expect_cell_value comes before a set_value, therefore it is not possible to consistently place expect_cell_value in expected. Ordering is important. To place expect_cell_value in expected, we would need to redefine how expect_cell_value works so that it may refer to a point in time before/after certain other operations.
