Set version to 0.30.1-hf2

When specifying that a result should be rounded up,
the code rounded up to a value suitable for a non-xrp
amount. When called with an xrp amount, if that rounded-up
value was less than one drop, the code rounded down to zero.

This could cause funded offers to be removed as unfunded.

-/** Structured, multi-threaded access to a shared state.
-
-    This container combines locking semantics with data access semantics to
-    create an alternative to the typical synchronization method of first
-    acquiring a lock and then accessing data members.
-
-    With this container, access to the underlying data is only possible after
-    first acquiring a lock. The steps of acquiring the lock and obtaining
-    a const or non-const reference to the data are combined into one
-    RAII style operation.
-
-    There are three types of access:
-
-    - Access
-        Provides access to the shared state via a non-const reference or pointer.
-        Access acquires a unique lock on the mutex associated with the
-        container.
-
-    - ConstAccess
-        Provides access to the shared state via a const reference or pointer.
-        ConstAccess acquires a shared lock on the mutex associated with the
-        container.
-
-    - ConstUnlockedAccess
-        Provides access to the shared state via a const reference or pointer.
-        No locking is performed. It is the callers responsibility to ensure that
-        the operation is synchronized. This can be useful for diagnostics or
-        assertions, or for when it is known that no other threads can access
-        the data.
-
-    - UnlockedAccess
-        Provides access to the shared state via a reference or pointer.
-        No locking is performed. It is the callers responsibility to ensure that
-        the operation is synchronized. This can be useful for diagnostics or
-        assertions, or for when it is known that no other threads can access
-        the data.
-
-    Usage example:
-
-    @code
-
-    struct State
-    {
-        int value1;
-        String value2;
-    };
-
-    using SharedState = SharedData <State>;
-
-    SharedState m_state;
-
-    void readExample ()
-    {
-        SharedState::ConstAccess state (m_state);
-
-        print (state->value1);   // read access
-        print (state->value2);   // read access
-
