fix: remove temporary esplora panic handling

[reez]

Description

Removes the temporary catch_unwind wrappers added in #863.

Notes to the reviewers

• bdk-ffi#869 tracked removing the temporary wrappers after upstream fixes landed.
• bdk#1971 fixed the wrong network panic that originally prompted the workaround.
• bdk#2053 added my upstream stop gap panic fix.
• bdk#2148 backported that fix into bdk_esplora 0.22.2, which bdk-ffi now uses.
