Version 1.41.1

Adds support for defining colours for specific field values in dashboard visualisations.

You can define colours for values by field using an additional configuration file called dashboard_colours.toml that can be placed either
in /etc/bigsdb (for global use) or within a database configuration directory. The format is as follows:

 'eav_Bexsero_reactivity' = {
      'exact match'       = '#2ca02c',
      'cross-reactive'    = '#ff7f0e',
      'none'              = '#d62728',
      'insufficient data' = '#888888',
      'No value'          = '#aaaaaa'
 }
 'eav_Trumenba_reactivity' = {
      'exact match'       = '#2ca02c',
      'cross-reactive'    = '#ff7f0e',
      'none'              = '#d62728',
      'insufficient data' = '#888888',
      'No value'          = '#aaaaaa'
 }
 's_1_clonal_complex' = {
      'ST-11 complex'      = 'yellow',
      'ST-41/44 complex'   = 'green'
 }

Field names are prefixed as follows:

• f_ Standard provenance fields, e.g. f_country

• e_ Extended attribute fields, e.g. e_country||continent (continent attribute linked to country)

• eav_ :ref:Sparely-populated fields<sparsely_populated_fields>, e.g. eav_Bexsero_reactivity

• s_ Scheme fields, e.g. s_1_clonal_complex (clonal complex field in scheme 1)

This works for pie, doughnut, bar, and pie charts. Note that if you define any values for a field then any value not defined will be shown as light grey in the visualisation.
