rs-v0.1.2

What's Changed

• fix doc publish action by @aastopher in #23
• patch docs by @aastopher in #24
• verify align hash output with imagehash by @aastopher in #25
• verify align hash output with imagehash by @aastopher in #26

Full Changelog: py-v0.1.3...rs-v0.1.2

aHash

• Reversed Bit Order:
  Now uses 1 << (63 - i) so that the most significant bit corresponds to the first pixel, matching imagehash’s convention.

---

mHash

• Reversed Bit Order:
  Bit order is reversed (using 1 << (63 - i)) to align with other hash types.
• Optimized Median Calculation:
  Uses Rust’s select_nth_unstable to compute the median in O(n) time instead of a full sort.

---

dHash

• Optimized Loop Structure:
  Retrieves the first pixel outside the inner loop (iterating from x = 1 to 8) to avoid redundant calls.

---

pHash

• Refined DCT Processing:
  Applies the DCT row‑wise and then column‑wise in place using a fixed‑size temporary array.
• DC Exclusion in Median Calculation:
  Extracts the top‑left 8×8 DCT coefficients and excludes the DC component when computing the median.
• O(n) Median Computation:
  Uses select_nth_unstable_by to find median in O(n).
• Reversed Bit Order:
  Final hash bits are reversed (using 1 << (63 - i)) for consistency with the other algorithms.
• Result:
  Produces a pHash that is consistent with imagehash.

---

wHash (Wavelet Hash)

• Reversed Bit Order:
  Now uses 1 << (63 - i) so that the most significant bit corresponds to the first pixel, matching imagehash’s convention.
• Haar Transform via dwt Crate:
  Implement Haar transform functions from the dwt crate.
• Zeroing DC Coefficient:
  Immediately zero out the DC coefficient after forward transform.
• O(n) Median Calculation:
  Clones transformed pixel vector and uses select_nth_unstable_by to find median in O(n).
• Hash Generation:
  Iterates over the reconstructed coefficients from the inverse Haar transform, setting bits based on the median, to conform to imagehash’s output.
• Result:
  Produces a wHash that is consistent with imagehash.

---

Each change was made to improve performance, and ensure consistent bit ordering across all hash types, and simplify the implementations and align hash output with imagehash for consistency.
