Tanaka-Kasuga-Yamashita-Yazaki 6A-D and MikkawyEisa tableaus missing fsal and adaptiveorder

[ChrisRackauckas-Claude]

Migrated from SciML/DiffEqDevTools.jl#71 (reported by @emca1).

Five tableau constructors are missing fsal=true, adaptiveorder=5, and αEEst in their return values:

• constructTanakaKasugaYamashitaYazaki6A
• constructTanakaKasugaYamashitaYazaki6B
• constructTanakaKasugaYamashitaYazaki6C
• constructTanakaKasugaYamashitaYazaki6D
• constructMikkawyEisa

Currently they return:

ExplicitRKTableau(A, c, α, 6, stability_size = ...)

They should return:

ExplicitRKTableau(A, c, α, 6, adaptiveorder = 5, αEEst = αEEst, fsal = true, stability_size = ...)

The αEEst data is computed in the function bodies but never passed to the constructor.

Verified still present as of 2026-03-30:

constructTanakaKasugaYamashitaYazaki6A: order=6, adaptiveorder=0, fsal=false, αEEst_len=0
constructTanakaKasugaYamashitaYazaki6B: order=6, adaptiveorder=0, fsal=false, αEEst_len=0
constructTanakaKasugaYamashitaYazaki6C: order=6, adaptiveorder=0, fsal=false, αEEst_len=0
constructTanakaKasugaYamashitaYazaki6D: order=6, adaptiveorder=0, fsal=false, αEEst_len=0
constructMikkawyEisa: order=6, adaptiveorder=0, fsal=false, αEEst_len=0
