ENH: Add Strain Lagrangian/Eulerian baselines (2 CID content-links)

Dedicated baselines for PR InsightSoftwareConsortium/ITK#6269
(Strain ingest), distinguishing the GreenLagrangian and EulerianAlmansi
strain forms from the existing shared Infinitesimal baseline. The
quadratic correction terms in these formulations are otherwise hidden
by the comparison tolerance against LineLoadStrain.mha.
