XML with entities like < get screwed up.

[forbesmyester]

Describe the bug
Escaping in XML does not work properly (when the string is already there)

To Reproduce
Save file as es_systems.cfg

<?xml version="1.0"?>
<systemList>
  <system>
    <name>retropie</name>
    <fullname>RetroPie</fullname>
    <path>/home/fozz/RetroPie/retropiemenu</path>
    <extension>.rp .sh</extension>
    <command>sudo /home/fozz/RetroPie-Setup/retropie_packages.sh retropiemenu launch %ROM% &lt;/dev/tty &gt;/dev/tty</command>
    <platform/>
    <theme>retropie</theme>
  </system>
</systemList>

and run the command

cat es_systems.cfg | dasel put string -p xml a .systemList x

Expected behavior
The </dev/tty > should have been retained, it also should have not generated an invalid document (it put in < instead of <)

Desktop (please complete the following information):

• OS: Ubuntu 20.04
• Version: development - 971ac93

Thanks for raising this issue @forbesmyester.

This is an issue with the XML parser being used - I've raised an issue with them: clbanning/mxj#84

This has been fixed as of v1.9.1: https://dasel.tomwright.me/s/0be94bad-15e5-4d37-b2d4-24bf054a856c

$ echo '<systemList>
  <system>
    <name>retropie</name>
    <fullname>RetroPie</fullname>
    <path>/home/fozz/RetroPie/retropiemenu</path>
    <extension>.rp .sh</extension>
    <command>sudo /home/fozz/RetroPie-Setup/retropie_packages.sh retropiemenu launch %ROM% &lt;/dev/tty &gt;/dev/tty</command>
    <platform/>
    <theme>retropie</theme>
  </system>
</systemList>' | dasel put string -p xml .newElement newValue
<doc>
  <newElement>newValue</newElement>
  <systemList>
    <system>
      <command>sudo /home/fozz/RetroPie-Setup/retropie_packages.sh retropiemenu launch %ROM% &lt;/dev/tty &gt;/dev/tty</command>
      <extension>.rp .sh</extension>
      <fullname>RetroPie</fullname>
