<p>This function must be called to enable the customization of <code>eyre::Report</code>
provided by <code>color-eyre</code>. This function should be called early, ideally
before any errors could be encountered.</p>
<p>Only the first install will succeed. Calling this function after another
report handler has been installed will cause an error. <strong>Note</strong>: This
function <em>must</em> be called before any <code>eyre::Report</code>s are constructed to
prevent the default handler from being installed.</p>
<p>Installing a global theme in <code>color_spantrace</code> manually (by calling
<code>color_spantrace::set_theme</code> or <code>color_spantrace::colorize</code> before
<code>install</code> is called) will result in an error if this function is called.</p>
