Modal window to edit metadata of a folio

[yinanazhou]

Users should be able to add and edit metadata, like the folio number and the manuscript info.

We could <fileDesc> to encode metadata about folio number and manuscript info, and also contributors (reference: https://music-encoding.org/guidelines/v5/content/metadata.html)

For our work, we could use this template:

<meiHead>
  <fileDesc>
    <titleStmt>
      <title>[Manuscript XXXX]</title>
      <title type="subtitle">[Folio no. XX],
        <identifier>[CantusDB UID, if we have it already at this stage]</identifier>
      </title>
      <title type="subtitle">an electronic transcription</title>
      <respStmt>
        <resp>Machine-readable transcription by:</resp>
        <corpName role="producer">DDMAL, McGill University</corpName>
        <resp>Optical Music Recognition with Rodan by:</resp>
        <persName role="encoder">[XXX XXX]</persName>
        <resp>Corrected with Neon by:</resp>
        <persName role="editor">[XXX XXX]</persName>
      </respStmt>
    </titleStmt>
  </fileDesc>
</meiHead>

@annamorphism @JoyfulGen @fujinaga, please let me know if this makes sense :)

I like it a lot! So is "encoder" the person who ran it in Rodan, and "editor" the person who corrected it in Neon?
