True if the basis_tex_format is ASTC LDR 4x4-12x12.

Evaluates against raw weights [0,64], or to ISE quantized weights, depending on weight_ise_index.

try_resize(0) sets the container to empty, but does not free the allocated block.

Note this is linear<->sRGB, NOT REC709 which uses slightly different equations/transfer functions. However the gamuts/white points of REC709 and sRGB

Sets all the sRGB-related options (m_perceptual, m_mip_srgb, m_ktx2_and_basis_srgb_transfer_function) to the specified value.

Writes bits to output in an endian safe way
