econio 0.1.0

• Added a NEWS.md file to track changes to the package.
• io_check_axes() is now called by io_leontief_inverse() and io_ghosh_inverse() to validate that input and output industry axes match before matrix inversion, preventing errors from mismatched tables.
• io_check_totals() now validates total_tolerance with a clearer error message.
• io_downstreamness() returns the column sums of the Leontief inverse, i.e. the output multiplier (backward linkage), with a normalize option to obtain the power of dispersion.
• io_input_coef(), io_output_coef(), io_leontief_inverse(), and io_ghosh_inverse() now report invalid open_economy values against the calling function with a clearer error message.
• io_reclass() now validates from_col, to_col, weight_col, weight_tolerance, and check_axes.
• io_spectral_embedding() is now marked as experimental.
• io_spectral_embedding() returns the Laplacian spectral embedding (Fiedler vector) of the domestic production network, minimizing the graph Dirichlet energy; pair it with io_trophic_level() for a directed supply-chain map.
• io_spectral_embedding(), io_trophic_incoherence() and io_trophic_level() now inform when they implicitly convert a competitive import type table to noncompetitive import type before building the industry network.
• io_spectral_embedding(), io_trophic_incoherence() and io_trophic_level() now inform and zero out negative domestic intermediate transactions (e.g. from byproduct treatment such as the Stone method) before building the industry network, instead of producing an ill-defined result.
• io_spectral_embedding() now reports an invalid dims argument with a clearer error message.
• io_streamness_length() is a new function that returns the total length of the supply chain passing through each industry, computed as the sum of io_upstreamness() and io_downstreamness(), following Antràs and Chor (2018).
• io_streamness_position() is a new experimental function that returns the net position of each industry within the supply chain, derived from io_upstreamness() and io_downstreamness(), with a type argument to choose between their difference, a [-1, 1]-bounded relative difference, or a log ratio.
• io_table_regional() and io_table_multiregional() now validate check_axes, competitive_import, and total_tolerance.
• io_table_to_competitive_import(), io_table_to_noncompetitive_import(), and io_table_to_regional() now validate their sector-name and tolerance arguments.
• io_table_to_noncompetitive_import() no longer leaves a leftover zero-valued import sector on the output axis when converting from a competitive import type table.
• io_total_input() and io_total_output() now validate same_region.
• io_trophic_incoherence() returns the trophic incoherence of the domestic production network.
• io_trophic_level() returns the directed-network trophic level of each industry, following MacKay, Johnson and Sansom (2020).
• io_upstreamness() returns the row sums of the Ghosh inverse, i.e. the forward linkage.
