Add Building ID Filter to `BuildStockRead` Methods

[sherryzuo]

What

Add native support for filtering by building IDs (bldg_id) in buildstockread methods (e.g., metadata and timeseries readers), allowing users to request only a specified subset of buildings.

Why

Many downstream workflows (e.g., cumulative adoption trajectories) require querying a select subset of building IDs across multiple pulls.

Currently, users must:

• Pull all buildings, then
• Filter in-memory or post-hoc

Native bldg_id filtering would:

• Reduce I/O and memory overhead

How

Add an optional building-ID filter argument to buildstockread methods.

Would it make sense to do this at the level of the BSR class, rather than individual methods?

added building_id filter to read_parquets, which changes the function call /signature of all downstream methods that call read_parquets (e.g. read_hourly_loadcurve etc.)
