Add LqdOxygen to all liquid storage tanks

[panarchist]

This PR does the following:

• Adds the file "Tank10.dds" to allow "LO2" to appear on the side of liquid containers
• Modifies the following items in 18 liquid container parts
  • MODULE FSfuelSwitch
    • resourceNames: adds the value "LqdOxygen" in order after LqdHydrogen
    • resourceAmounts: adds a value for LqdOxygen equal to the value used by Karborundum, Water, Chemicals, and Mulch in the correct order
    • InitialResourceAmounts: adds a 0 value in the correct order
    • tankCost: adds a value in the correct order equal to the value for LqdHydrogen x 1.24
    • tankMass: adds a 0 value in the correct order
  • MODULE FStextureSwitch2
    • textureNames: Adds an additional path reference in the correct order, with the Tank10.dds file appended to the string on all tanks which have path-to-file instead of path-to-directory
    • textureDisplayNames: Adds the value "LO2" immediately after LH2
    • fuelTankSetups: Adds the next sequential number at the end of the ordered list

Known issues: LqdHydrogen displays as "LH2" in the tank selector, but LqdOxygen displays by name - this is due to FStextureSwitch2 using the CRP localization files and pulling #LOC_CRP_LqdHydrogen_Abbreviation for LH2 and #LOC_CRP_LqdOxygen_DisplayName for LO2 (LOX). The resources are curated by different maintainers, so resolving it would require the RealFuels maintainer to add an entry for #LOC_CRP_LqdOxygen_Abbreviation with a value of "LO2" or "LOX" to be consistent with NFT's "LH2" abbreviation. If it is switched to "LOX", the Tank10.dds file would need to be edited accordingly.
