Ghana: Energy emission in BUR3

[JGuetschow]

The energy CO2 time-series from BUR3 show peaks for certain years. As we currently only have aggregate energy CO2 time-series available for use in PRIMAP-hist which are downscaled to the necessary categorical level the peaks appear in all energy CO2 time-series. However, they actually come from flaring. Flaring data are available in the NIR to BUR3. Read the flaring time-series to make the energy CO2 data more accurate.
