newmax was an integer variable kept as a string. Very ominous.
Moreover, memory management seems to be broken:
1) The string is never freed.
2) The string is passed as value from do_uemis_import() to
get_matching_dives(), which passes it as reference to
process_raw_buffer(), which may reallocate it, which means
that do_uemis_import() now possesses a pointer to a free()d
string.
Simplify all that by making newmax an integer variable and
passing it as a reference from do_uemis_import() to
get_matching_dives().

There were a number of fprintf()s that escaped the conversion
to report_info(), because they used "debugfile" instead of
"stderr" as target. However, debugfile was just #defined to
be stderr, so we might just use report_info() for consistency.

The uemis code is wild. It simply doesn't deallocate memory
and uses global variables. To get this under control, create
a "struct uemis" and make the functions exported by "uemis.h"
members of "struct uemis". Thus, we don't have to carry around
a parameter for the state of the importing process.
Turn a linked list of "helper" structures (one per imported dive)
into a std::unordered_map, to fix leaking of the helper structures.

Convert some C-style strings in uemis-downloader.cpp to std::string.
This has the side effect of fixing builds on Debian Trixie, which
currently fail with the (rather silly) error:
/build/subsurface-beta-202405060411/core/uemis-downloader.cpp: In function 'char* build_ans_path(const char*, int)':
/build/subsurface-beta-202405060411/core/uemis-downloader.cpp:290:32: error: '%s' directive output between 0 and 12 bytes may cause result to exceed 'INT_MAX' [-Werror=format-truncation=]
