Add option to render using full available height (rows)

[DanielSRS]

Currently if one wants to create an application that fills all available columns and rows, they need to create a component that listens to stdout size changes, like this:

import React from 'react';
import { Box, render, Text } from 'ink';
import useStdoutDimensions from 'ink-use-stdout-dimensions';

function Application() {
  const [columns, rows] = useStdoutDimensions();
  return (
    <Box width={columns} height={rows}>
      <Text>Content</Text>
    </Box>
  );
}

render(<Application />);

But ink already listens and recalculate layout when stdout resizes, but only for width (columns)

this PR adds an render option to also use height (rows) size when recalculating layout.

so, one only needs to pass an optional render option, like this:

import React from 'react';
import { render, Text } from 'ink';

function Application() {
  return (
    <Text>Content</Text>
  );
}

render(<Application />, {fullHeight: true});

Added:

• fullHeight render option
• an example that uses full height
