This change looks dramatic, but it's just separating out the already-split namespaces into separate top-level folders. In theory, every single one could be built into their own Nuget package. `SabreTools.Serialization` still builds the normal Nuget package that is used by all other projects and includes all namespaces.

///
|

/// "Weak externals" are a mechanism for object files that allows flexibility at
|
|
/// link time. A module can contain an unresolved external symbol (sym1), but it
|
|
/// can also include an auxiliary record that indicates that if sym1 is not
|
|
/// present at link time, another external symbol (sym2) is used to resolve
|
|
/// references instead.
|
|
///
|
|
/// If a definition of sym1 is linked, then an external reference to the symbol
|
|
/// is resolved normally. If a definition of sym1 is not linked, then all references
|
|
/// to the weak external for sym1 refer to sym2 instead. The external symbol, sym2,
|
|
/// must always be linked; typically, it is defined in the module that contains
|
|
/// the weak reference to sym1.
|
|
///
|
|
/// Weak externals are represented by a symbol table record with EXTERNAL storage
|
|
/// class, UNDEF section number, and a value of zero. The weak-external symbol
