bitfield_order and le/be prefixes do nothing on bitfields

tested on imhex revision https://github.com/WerWolv/ImHex/commit/c6045c7044668b5d9b6442aad837f888d4ba4933

bin file: 00 00 FE 00 00 FE 00 00

pattern:

import std.core;

bitfield DDSCaps2 {
    front: 9;
    Cubemap: 1;
    CubemapPositiveX: 1;
    CubemapNegativeX: 1;
    CubemapPositiveY: 1;
    CubemapNegativeY: 1;
    CubemapPositiveZ: 1;
    CubemapNegativeZ: 1;
    back: 16;
};

DDSCaps2 ltms[2] @ 0 [[bitfield_order(std::core::BitfieldOrder::LeastToMostSignificant, 32)]];
DDSCaps2 mtls[2] @ 0 [[bitfield_order(std::core::BitfieldOrder::MostToLeastSignificant, 32)]];
be DDSCaps2 big[2] @ 0;
le DDSCaps2 little[2] @ 0;

the values are always the same.

the expected outcome is one of two outcomes, either:

• back becomes 65024 on BE
• bitfield layout gets reversed

neither happens.

the former is necessary for fundamental bitset usage, the latter is necessary for flag enums (such as in this case where DDSCaps2 is a flag enum.

Start by reproducing the supplied bitfield pattern with the provided binary data on the referenced ImHex revision, then trace handling of bitfield_order and the le/be prefixes in the Pattern Language implementation. Done means these annotations produce the expected byte order or reversed bitfield layout, with the DDSCaps2 values differing as described.
