Query builder interface

[program--]

This PR bumps hfsubsetR to version 0.3.0.

Features

• Adds a query builder interface:

  Normal Interface

  get_subset(
    hl_uri = "gages-06752260",
    layers = c("divides", "network"),
    gpkg = "/path/to/my.gpkg",
    outfile = "my_subset.gpkg",
    overwrite = TRUE
  )

  Query Builder Interface

  query() |>
    query_set_id(identifier = "gages-06752260", type = "hl_uri") |>
    query_set_layers(layers = c("divides", "network")) |>
    query_set_sink(sink = "my_subset.gpkg", overwrite = TRUE) |>
    query_set_source(src = query_source_sf("/path/to/my.gpkg")) |>
    query_subset()

  This change is primary for two reasons: (1) to ensure maintainability for hfsubsetR in the future, as the query builder interface allows us to maintain decoupling of the components that make up a query; and, (2) allows increased flexibility for hfsubsetCLI in constructing queries from user parameters.

Fixes

• Changes findOrigin and findOriginQuery to snake_case to match rest of package.
• Fixes an issue with S3 dispatch on finding origins, where dplyr throws on comparison with an identifier-classed character (used as.character() to resolve).
