fix: detect h3 column in arrow

[lixun910]

Fix an issue that h3 column can not be detected when using arrow table.

in arrowSchemaToFields() function:

getFieldsFromData() was first used to detect H3 columns:

const keplerFields = getFieldsFromData(sample, headerRow);

If there is a H3 column, it will be recorded in keplerFields. However, when go through the table.schema.fields, the type and analyzeType are initialized as string and AnalyzerDATA_TYPES.STRING since the H3 column is VARCHAR.

So, there is a missing case for H3

    } else if (fieldTypeSuggestion === 'VARCHAR' && keplerField.type === ALL_FIELD_TYPES.h3) {
      // when kepler detected h3 column using getFieldsFromData(), set type to h3 and analyzerType to H3
      type = ALL_FIELD_TYPES.h3;
      analyzerType = keplerField.analyzerType;
    } else {

Otherwise, the type will be overwritten as 'string', and analyzeType will be AnalyzerDATA_TYPES.STRING
