Fix fill missing in industry sector ratios intermediate

[tgi-climact]

Changes proposed in this Pull Request

I found a strange behaviour of build_industry_sector_ratios_intermediate. When looking to intermediate steps between current and futur industry, missing values were wrongly filled with futur data.

I suggest to use futur data only when we miss the full description of the technology (carrier whise).

Here is an example of Ammonia in Belgium where we see a mix of current and futur data.

Ammonia / BE	new	new	new	old	old	old
MWh/tMaterial	2020	2030	2050	2020	2030	2050
elec	0.2473	0.17311	0	0.2473	0.17311	0
coal	0	0	0	0	0	0
coke	0	0	0	0	0	0
biomass	0	0	0	0	0	0
methane	0	0	0	0	0	0
hydrogen	5.93	4.151	0	5.93	4.151	0
heat	0	0	0	0	0	0
naphtha	0	0	0	0	0	0
ammonia	0	1.5498	5.166	5.166	5.166	5.166
process emission	0	0	0	0	0	0
process emission from feedstock	0	0	0	0	0	0

I used to following values for sector_ratios_fraction_future:

  sector_ratios_fraction_future:
    2020: 0.0
    2025: 0.1
    2030: 0.3
    2035: 0.5
    2040: 0.7
    2045: 0.9
    2050: 1.0
