Allow dynamic columns

[skorphil]

Is your feature request related to a problem? Please describe.
I have data structure with dynamic properties (some of them are constant, but others can be anything)
Currently tinyBase do not support this:

export const persistentStateStore =
createStore().setTablesSchema(tinyBasePersistentStoreSchema);

persistentStateStore.setTables({
appState: {currentJournalDirectory:
{
newProperty: "test", // Object literal may only specify known properties, and 'test' does not exist in type
selectedCurrency: "usd"
}}
})

Describe the solution you'd like
Allow dynamic columns

By default, all TinyBase cells/columns are dynamic. You can add any to any row at runtime.

In your case you are creating a schema, which then disallows arbitrary columns. I would recommend you have one store with a schema (if you want constrained columns) and another with no schema (which will let you write what you like).

Does that help?
