Sunburst plots override font size and don't position unreadable labels outside

Hi everyone,

just discovered sunburst plots and am loving them! Besides the problem of text orientation that is momentarily being solved, I am wondering why it is possible to style outsidetextfont but not possible to actually place text outside the chart (at least for the last level). Similarly to pie charts, I would expect to find a textposition = 'outside' parameter. At the moment, for tiny wedges, the labels are being squeezed in no matter what, ignoring the font sizes given in insidetextfont AND textfont. Example:

import plotly.graph_objects as go
data = pd.DataFrame.from_dict({'key': {0: '#iii',
  1: '#vi',
  2: 'I',
  3: 'III',
  4: 'V',
  5: 'bII',
  6: 'i',
  7: 'ii',
  8: 'iii',
  9: 'iv',
  10: 'v',
  11: 'major',
  12: 'minor'},
 'duration': {0: 4.0,
  1: 12.0,
  2: 85.0,
  3: 202.0,
  4: 4.0,
  5: 4.5,
  6: 655.0,
  7: 5.0,
  8: 4.0,
  9: 33.5,
  10: 54.5,
  11: 295.5,
  12: 768.0},
 'parent': {0: 'minor',
  1: 'minor',
  2: 'major',
  3: 'major',
  4: 'major',
  5: 'major',
  6: 'minor',
  7: 'minor',
  8: 'minor',
  9: 'minor',
  10: 'minor',
  11: '',
  12: ''}})
fig =go.Figure(go.Sunburst(
    labels=data.key,
    parents=data.parent,
    values=data.duration,
    branchvalues="total", 
    textfont = {'size': 20},
    insidetextfont = {'size': 20},
    textinfo = "label+percent parent",
    #textposition='outside' <-- this option is missing
    ))
fig.show()

Empieza ejecutando la reproducción de Python proporcionada con go.Sunburst y compara la colocación de las etiquetas y el comportamiento del tamaño de fuente con el comportamiento del pie-chart mencionado en el issue. Rastrea las opciones de las etiquetas de sunburst y determina el comportamiento esperado para la colocación fuera, las cuñas diminutas y textfont/insidetextfont; se considera terminado cuando la opción solicitada y el comportamiento de dimensionamiento funcionan en el ejemplo reportado.
