Xtrack version 0.48.0

Changes:

• New features in Line.twiss:
  • Initial conditions can be provided at any point in the selected range.
  • Initial conditions can be provided as keyword arguments, e.g. line.twiss(ele_start='ip8', ele_stop='ip2', ele_init='ip1', betx=1., bety=2.).
  • Twiss range can extend across the end of the line (useful to avoid unnecessary line cycle).
  • ele_co_search can be provided to periodic twiss to perform the closed orbit search at a given point in the line (instead of start line). Useful to avoid failures when large orbit bumps extend across the start of the line.
